Pairing energies of 150 < A < 190 deformed nuclei for the fixed quantum states of odd nucleons

Resumo

Pairing energies are calculated from empirical values of the masses of deformed nuclei in the 150 < A < 190 region using a new expression that includes the mass of only a single odd-neutron or odd-proton nucleus. This allows us to draw conclusions on variations in pairing energies along the chain of isotones or isotopes. The accuracy of the proposed expression is examined on the basis of the familiar Garvey–Kelson mass relation.
