Abstract

Based on the existing correlation between the deformation energy and the lowest excitation energy, estimates were obtained for the energies of the 2₁⁺ -states of lanthanide group nuclei. The considered systematics of energy relations in the rotational band also made it possible to obtain estimates for the 4₁⁺ - and 6₁⁺ -states of this group of nuclei.
