Nuclear physics is the field of physics that studies atomic nuclei and their constituents and interactions, in addition to the study of other forms of nuclear matter. Nuclear physics should not be confused with atomic physics , which studies the atom as a whole, including its electrons .
The study of proton emission has aided the understanding of nuclear deformation, masses and structure, and it is an example of quantum tunneling. Two examples of nuclides that emit neutrons are beryllium-13 (mean life 2.7 × 10 −21 s) and helium-5 (7 × 10 −22 s). Since only a neutron is lost in this process, the atom does not gain or lose ...
Equations. Mass number. A = (Relative) atomic mass = Mass number = Sum of protons and neutrons. N = Number of neutrons. Z = Atomic number = Number of protons = Number of electrons. A = Z + N {\displaystyle A=Z+N\,\!} Mass in nuclei. M'nuc = Mass of nucleus, bound nucleons. MΣ = Sum of masses for isolated nucleons.

Harald Anton Enge (September 28, 1920, Fauske Municipality, Nordland, Norway [1] – April 14, 2008, Middlesex County, Massachusetts) [2] was a Norwegian-American experimental nuclear physicist and inventor of instrumentation used in nuclear physics. He is known for the Enge split-pole spectrograph, which became a standard instrument of nuclear ...
Bernard Cohen (physicist) Bernard Leonard Cohen (June 14, 1924 – March 17, 2012) was born in Pittsburgh, [1] [self-published source?] and was Professor Emeritus of Physics at the University of Pittsburgh. Professor Cohen was a staunch opponent of the so-called Linear no-threshold model (LNT) which postulates there exists no safe threshold for ...
In nuclear physics, the Geiger–Nuttall law or Geiger–Nuttall rule relates the decay constant of a radioactive isotope with the energy of the alpha particles emitted. Roughly speaking, it states that short-lived isotopes emit more energetic alpha particles than long-lived ones. The relationship also shows that half-lives are exponentially ...
