Even and odd atomic nuclei

In nuclear physics, properties of nuclei depend on parity or even its atomic number Z, neutron number N and, consequently, their sum, the mass number A. Most importantly, the fragmentation of both Z and N tends to decrease nuclear energy, making odd nuclei, generally, less stable. This effect is not only experimentally observed, but is included in the semiempirical mass formula and explains some of the other nuclear models, such as the nuclear shell model. This difference of nuclear binding energy between neighbouring nuclei, especially of odd - its a isobars, has important consequences for beta decay. In addition, the nuclear spin is an integer mostly 0 for all even - a nuclei and a non-integer half-integer for all odd cores. The ratio of neutron–proton is not the only factor affecting nuclear stability. Adding neutrons to isotopes can vary their nuclear spins and nuclear shapes, as a result of differences in the neutron capture cross sections and gamma-ray spectroscopy and nuclear magnetic resonance properties. If too many or too few neutrons are present with respect to nuclear energy optimum, the nucleus becomes unstable and subject to certain types of nuclear decay. Unstable nuclides with a nonoptimal number of neutrons or protons decay by beta-decay, including positron decay, electron capture, or other means, such as spontaneous fission and cluster decay.
