Furthermore, for odd odd nuclei, there are two unpaired nucleons to be considered, as in superposition of these.
2.
Furthermore, for odd-odd nuclei, one has to consider the two " last " nucleons, as in superposition of them.
3.
Magnitude of the pairing term in the total binding energy for even-even and odd-odd nuclei, as a function of mass number.
4.
The pairing term \ pm e / A ^ { 7 / 4 } is purely empirical; it is + for even-even nuclei and-for odd-odd nuclei.
5.
While the best known neutron reactions are neutron scattering, neutron capture, and nuclear fission, for some light nuclei ( especially odd-odd nuclei ) the most probable reaction with a thermal neutron is a transfer reaction:
6.
Due to the great rarity of odd odd nuclei, almost all the primordial isotopes of the alkali metals are odd even ( the exceptions being the light stable isotope lithium-6 and the long-lived radioisotope potassium-40 ).
7.
Odd-odd primordial nuclides are rare because most odd-odd nuclei are highly unstable with respect to beta decay, because the decay products are even-even, and are therefore more strongly bound, due to nuclear pairing effects.
8.
The pairing term ( positive for even-even and negative for odd-odd nuclei ) was derived from the binding energy data in : G . Audi et al .,'The AME2012 atomic mass evaluation', in Chinese Physics C 36 ( 2012 / 12 ) pp . 1287 1602.
9.
Deuterium is one of only five stable nuclides with an odd number of protons and an odd number of neutrons . (,,,,; also, the long-lived radioactive nuclides,,, occur naturally . ) Most odd-odd nuclei are unstable with respect to beta decay, because the decay products are even-even, and are therefore more strongly bound, due to orbital angular momentum.
