  Introduction to Atomic Physics | Atomic Physics | Science | atomicarchive.com
Atomic energy is the source of power for both nuclear reactors and nuclear weapons.
He also proposed that the nucleus has a positive charge and is surrounded by negatively charged electrons, which had been discovered in 1897 by J.
This theory of atomic structure was complemented by Niels Bohr in 1913.

  Atomic physics   (Site not responding. Last check: )
Atomic physics (or atom physics) is physics of the electron hull of atoms.
However, physcists distinguishbetween atomic physics (dealing with the effects of the electron hull and thenucleus's overall spin and electriccharge) and nuclear physics (dealing with the forces within theatomic nuclei and reactions that alter, fuse or split them).
The beginning of atomic physics is marked by the discovery and scrutinious study of spectral lines.

 Theoretical Principles of Plasma Physics and Atomic Physics
Collision Frequency: The concept of a collision frequency is probably the most important one in plasma physics (and the physics of gases in general) when it comes to assessing the significance of the individual physical processes.
There is also evidence that this aspect is of relevance for collisional excitation of atomic states by electrons or ions as the relevant cross section is apparently enhanced if the medium becomes continuous with regard to the wavelength of the equivalent radiative transition (see /research/striapot.htm).
Emission Rate: The intensity of radiation emitted during a discrete atomic transition is determined by the Level Population and the Atomic Decay Probability.

 Atomic Physics at NCSU
Atomic Physics is concerned with describing the electron clouds surrounding the nuclei of atoms and the way these clouds are influenced by the presence of fields, either static or dynamic.
Atomic properties such as energies, wave functions, lifetimes, isotope shifts, fine and hyperfine structures are calculated for bound states as well as highly-excited resonance systems.
This research in atomic collisions, which is partly conducted using radiation from the electron storage ring at the National Institute of Standards and Technology in Gaithersburg, Maryland, has important applications which can be used in the study of both plasma diagnostics and astrophysical observations.

 Math Trek: Celestial Atomic Physics, Science News Online, Sept. 10, 2005
Indeed, the mathematics describing the motion of gravitationally interacting bodies in space closely parallels the mathematics describing the motion of the smallest particles of atomic and molecular physics.
Atomic physicists and chemists face a similar challenge in modeling chemical reactions and computing ionization rates of atoms and molecules.
So, theory from atomic and molecular physics can be used on a much grander, celestial scale, and celestial mechanics can provide insights into atomic and molecular interactions.

 UA Physics Department - Atomic And Molecular Physics
The study of the structures at the center of the atom is the realm of high energy and nuclear physics; the way atoms themselves behave and the way they interact with one another is the domain of atomic and molecular physics.
For instance, the detailed understanding of atomic and molecular collisions is crucial to branches of physics such as plasma physics and astrophysics.
For example, we are exploring the many-body dynamics of cold atoms in 1D geometries as appropriate to atomic waveguides, and this impacts the basic understanding of matter-wave coherence and also has implications for proposed atom wave sensors.

The fields of atomic physics and particle physics provide many valuable insights into the life cycles of stars, the forms of spaceborne radiation, the way we can use spectra to study distant objects, and many other topics in space science.
The discipline of atomic physics concerns itself with atoms, the particles from which atoms are made, and the various energy states that atoms can take on.
The "laws" of physics at atomic and subatomic scales are so different from those we observe in our "normal" daily experiences that physicists had to invent a whole new field to describe them.

 Niels Bohr - Biography
In 1913-1914 Bohr held a Lectureship in Physics at Copenhagen University and in 1914-1916 a similar appointment at the Victoria University in Manchester.
In 1916 he was appointed Professor of Theoretical Physics at Copenhagen University, and since 1920 (until his death in 1962) he was at the head of the Institute for Theoretical Physics, established for him at that university.
Hereby he could show how deeply the changes in the field of physics have affected fundamental features of our scientific outlook and how the consequences of this change of attitude reach far beyond the scope of atomic physics and touch upon all domains of human knowledge.

 Physics Today December 2003 - Stern and Gerlach: How a Bad Cigar Helped Reorient Atomic Physics
Among them are the prototypes for nuclear magnetic resonance, optical pumping, the laser, and atomic clocks, as well as incisive discoveries such as the Lamb shift and the anomalous increment in the magnetic moment of the electron, which launched quantum electrodynamics.
A new center for experimental physics at the University of Frankfurt was recently named in honor of Stern and Gerlach (see figure 1).
Because the interaction energy of atoms with the field differs with their orientation, it remained a mystery how splitting could occur when atoms entered the field with random orientations and their density in the beam was so low that collisions did not occur to exchange energy.

 Atomic & Molecular Physics [JILA]
JILA makes major contributions to four vibrant research areas in the field of atomic and molecular physics: ultracold atoms, the control of atoms, molecules, and electrons with light, dense atomic vapors, and cold molecules.
Their ground-breaking studies are helping to redefine atomic physics, a field that has enjoyed explosive growth because of the ability of theory to accurately describe observed phenomena and give predictive support to experiments.
For example, one optical physicist is studying the fundamental interactions of light with dense atomic vapors and several groups are collaborating to develop the ultrafast lasers, high-resolution microscopy, and coherent spectroscopy required by today's atomic and molecular physicists.
