An investigation was made to determine with which N and Z numbers nuclear deformation effects are to be associated, whether or not any of the subshells are filled in the heavy nucleus range, and the energy associated with filling of the subshells and the effect of deformation. The energy increments required to add neutrons and protons was considered and singularities were noted in the energies at N = 130, 156, 144, and 152 for neutron addition and at Z = 86, 92, and 96 for proton adddtion. An examination of the lowest rotational levels led to the conclusion that the numbers Z = 86 and N = 130 are to be associated with a sharp increase in deformation. The total effect of nuclear deformation is about 0.7 Mev for neutron and protons. The subshell effect is about 0.2 Mev except for N = 152 for which the effect is of the order of 0.4 Mev. (J.S.R.)
