23. Discussions With Einstein On Epistemological Problems In Atomic Physics Report by Niels Bohr of his discussions with Albert Einstein over many years on the epistemological implications of quantum theory. http://www.marxists.org/reference/subject/philosophy/works/dk/bohr.htm

Niels Bohr (1949) Discussions with Einstein on Epistemological Problems in Atomic Physics Source : From Albert Einstein: Philosopher-Scientist (1949), publ. Cambridge University Press, 1949. Neils Bohr's report of conversations with Einstein and Einstein's reply. WHEN invited by the Editor of the series, Living Philosophers With unfailing intuition Einstein thus was led step by step to the conclusion that any radiation process involves the emission or absorption of individual light quanta or "photons" with energy and momentum E hf and P hs respectively, where h is Planck's constant, while f and s are the number of vibrations per unit time and the number of waves per unit length, respectively. Notwithstanding its fertility, the idea of the photon implied a quite unforeseen dilemma, since any simple corpuscular picture of radiation would obviously be irreconcilable with interference effects, which present so essential an aspect of radiative phenomena, and which can be described only in terms of a wave picture. The acuteness of the dilemma is stressed by the fact that the interference effects offer our only means of defining the concepts of frequency and wavelength entering into the very expressions for the energy and momentum of the photon. In this situation, there could be no question of attempting a causal analysis of radiative phenomena, but only, by a combined use of the contrasting pictures, to estimate probabilities for the occurrence of the individual radiation processes. However, it is most important to realize that the recourse to probability laws under such circumstances is essentially different in aim from the familiar application of statistical considerations as practical means of accounting for the properties of mechanical systems of great structural complexity. In fact, in quantum physics we are presented not with intricacies of this kind, but with the inability of the classical frame of concepts to comprise the peculiar feature of indivisibility, or "individuality," characterising the elementary processes.

Atomic/Radiative Physics It was the study of atoms that led to the development of quantum mechanics and the birth of modern physics in the first half of this century and atomic physics continues to be a fertile field for unrevealing the elementary laws of nature. Current investigations of phenomena on the atomic scale provide information on the limits of electrodynamics, the interpretation of quantum mechanics, and electron-quark weak interactions. Key questions regarding atomic structure also remain unanswered: the nature of Rydberg states, relativistic and correlation effects in heavy atoms, and atoms in strong external electric and magnetic fields. Collisional processes in atoms photoionization, electron-ion scattering, and ion-atom interactions not only address issues of fundamental physics but also have applications in many other fields of physics such as space physics, condensed matter physics, and plasma physics.

Research in Atomic and Molecular Physics The atomic, molecular, and optical physics programs at LSU bring together the theoretical work of Drs. Rau and Schafer , and Boyd Professor O'Connell (also see condensed matter/solid state physics). Topics under investigation in atomic theory by this group include scattering, excitation, and ionization in electron-atom and electron-ion collisions, atoms in strong fields, and photo absorption. The roles of correlation, resonance, and relativistic effects are studied. In quantum optics, Dr. O'Connell studies energy shifts in radiation, as well as non-Markovian effects in quantum optics. Dr. Schafer works on intense laser effects on atoms, including multi-photon absorption and ionization and the production of high harmonics. Working with faculty members in this group are postdoctoral associates and a number of graduate students. In addition, there are ties to the experimental work in atomic physics in the Department of Chemistry, particularly in the laboratories of Drs. Hopkins and Poliakoff , and Boyd Professor McGlynn . Students from the department in Dr. Poliakoff's group study vibrationally resolved excitation of small molecules with photons of energy 10-200 eV at the CAMD Synchrotron facility. (see page 4).

Atomic, molecular, and optical physics From Wikipedia, the free encyclopedia. (Redirected from Atomic, Molecular, and Optical physics Atomic molecular , and optical physics is the study of matter -matter and light -matter interactions on the scale of single atoms or structures containing a few atoms. The three areas are grouped together because of their interrelationships, the similarity of methods used, and the commonality of the energy scales that are relevant. Physicists sometimes abbreviate the field as AMO physics Atomic physics is distinct from nuclear physics , despite their association in the public consciousness. Atomic physics is not concerned with the intra-nuclear processes studied in nuclear physics, although properties of the nucleus can be important in atomic physics (e.g., hyperfine structure Molecular physics focuses on multi-atomic structures and their internal and external interactions with matter and light. Optical physics is distinct from optics in that it tends to focus not on the control of classical light fields by macroscopic objects, but on the fundamental properties of optical fields and their interactions with matter in the microscopic realm. All three areas include both classical and quantum treatments.

The experiment (Rutherford): Most of the atom is empty space! All of the positive charge is concentrated in a very small space! The modern model of the atom is born. But: 1. Does not explain why there are spectral lines. 2. Classical electrodynamics rears its ugly head: orbiting electrons should continuously radiate light, lose energy, and fall into the nucleus. They don’t. 28.2 Atomic Spectra Each element has its own characteristic “fingerprint”. A heated gas emits emission lines. The same gas, when placed between a bright continuous background source and the observer produces absorption lines at those same wavelengths.

Transferring you to the updated Atomic Physics Page....... Next: Condensed Matter Physics Up: Research Areas Previous: Astronomy and Astrophysics Atomic Physics Atomic physics is concerned with high precision measurements that test our very basic understanding of many-electron systems. Apart from its fundamental interest, atomic physics has implications for plasma physics, astrophysics, and chemistry. Atomic physics at the University of Kentucky is focussed on the structure and evolution in time of excited states of atoms, the interaction of excited atoms with strong external fields, and collisions between excited atoms. Professor Keith MacAdam Through the process of photoexcitation, the outermost electron of an atom can be raised into a highly excited orbital state; these atoms are called Rydberg atoms. They are characterized by extremely large diameters (frequently 1000 times their normal size), enhanced collision probabilities, and an extreme sensitivity to the effects of externally applied electromagnetic fields. A sufficiently strong static electric field can actually tear away the highly excited electron, a process called field ionization. Rydberg atoms may be studied in great detail both experimentally and theoretically. Among the features amenable to these comparisons are energy level shifts, positions, and widths; the appearance of continua; autoionization rates; and the transfer of population among states. The effects of time-varying electric fields on atoms are significantly more complicated than the effects of static fields since population may be transferred among levels in a manner that depends on the rate at which the field changes. Strong oscillating fields-e.g., intense laser light or strong microwaves-may cause absorption and emission of several photons simultaneously in a single atom and give the participating atoms unusual absorption and ionization properties that have no counterpart in the classical theory of light.
