Bose-Einstein nucleus | | element | boson | Bose-Einstein statistics | | | 0 | uncertainty principle | | | Nucleus of even A-number (i.e., those with integral spin) (cf. Fermi-Dirac nuclei). Bose-Einstein nuclei do not obey the exclusion principle, and their ground state has zero angular momentum. | non-zero | | | |
deuteron | | element | | | | charged particle | | uncertainty principle | | | The nucleus of a deuterium atom. md = 2.01355 amu. | 1 | | d | |
even-odd nucleus | | element | fermion | Fermi-Dirac statistics | | | half-integral | exclusion principle | | | Nucleus that contain even numbers of protons but odd numbers of neutrons. | non-zero | | | |
Fermi-Dirac nuclei | | element | nucleus | | | | | uncertainty principle | | | Nuclei of odd A-number (i.e., nuclei that do not have integral spin) (cf. Bose-Einstein nuclei). Fermi-Dirac nuclei therefore obey the exclusion principle (q.v.). | non-zero | | | |
isomer | | element | nucleus | | | | | uncertainty principle | | | Nucleus with the same A and Z numbers but in different energy states. | non-zero | | | |
isotone | | element | nucleus | | | | | uncertainty principle | | | Nucleus with the same number of neutrons but with different A and Z numbers. | non-zero | | | |
isotope | | element | nucleus | | | | | uncertainty principle | | | Two nuclei with the same number of protons but different numbers of neutrons are said to represent the same element, but different isotopes. For example, helium-3, with two protons and one neutron in each nucleus, and helium-4, with two protons and two neutrons, are two different isotopes of helium. For another example, see deuterium. | non-zero | | | |
nuclide | | element | nucleus | | | | | uncertainty principle | | | A species of atomic nucleus, analogous to the word "isotope" for a species of atom. The word is also used to distinguish between atomic nuclei that are in different energy states. | non-zero | | | |
proton | | nucleus | | Fermi-Dirac statistics | 3 | charged particle | 1/2 | uncertainty principle | 939 MeV | | A positively charged elementary particle; the nucleus of a hydrogen atom. Mass of proton 1.00728 amu = 1.6726 × 10-24 g = 1836.12 me. | 1 | -has source: Hopkins, J. 1976 Glossary of Astronomy and Astrophysics, University of Chicago Press | p | two up quarks and one down quark |
