The term atomic physics can be associated with nuclear power and nuclear weapons, due to the synonymous use of atomic and nuclear in standard English. Physicists distinguish between atomic physics—which deals with the atom as a system consisting of a nucleus and electrons—and nuclear physics , which studies nuclear reactions and special ...
J. Robert Oppenheimer (born Julius Robert Oppenheimer; / ˈ ɒ p ən h aɪ m ər / OP-ən-hy-mər; April 22, 1904 – February 18, 1967) was an American theoretical physicist who served as the director of the Manhattan Project's Los Alamos Laboratory during World War II.
Pranawachandra Deshmukh [1] [2] is an Indian physicist and educator renowned for his contributions to theoretical atomic physics, atomic collisions, light-matter interactions, ultrafast atomic processes, and applications of Lambert W Function in pure and applied physics.
James K. Freericks (born 1963) is an American physicist and endowed chair at Georgetown University. He has worked in fields of condensed matter physics, mathematical physics, atomic physics, nonequilibrium physics, quantum computation, and quantum mechanics pedagogy.
Richard Phillips Feynman (/ ˈ f aɪ n m ə n /; May 11, 1918 – February 15, 1988) was an American theoretical physicist.He is best known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, the physics of the superfluidity of supercooled liquid helium, and in particle physics, for which he proposed the parton model.
In 1900, Max Planck derived the average energy ε of a single energy radiator, e.g., a vibrating atomic unit, as a function of absolute temperature: [24] = / (), where h is the Planck constant, ν is the frequency, k is the Boltzmann constant, and T is the absolute temperature. The zero-point energy makes no contribution to Planck's original ...
In atomic physics and quantum chemistry, the Aufbau principle (/ ˈ aʊ f b aʊ /, from German: Aufbauprinzip, lit. 'building-up principle'), also called the Aufbau rule, states that in the ground state of an atom or ion, electrons first fill subshells of the lowest available energy, then fill subshells of higher energy.
The final atomic state thus has two holes, one in the 2s orbital and the other in the 2p orbital. (b) illustrates the same process using X-ray notation , KL 1 L 2,3 . The Auger effect ( / oʊ ˈ ʒ eɪ / ; French pronunciation: [ˈ/o.ʒe/] ) or Auger−Meitner effect is a physical phenomenon in which atoms eject electrons .
