The deformation of the ground and excited states in the Ag and Sn nuclei

Abstract

The microscopic calculation of the potential energies in the ground and excited states of Ag and Sn nuclei has been performed. The single particle Nilsson potential and the shell correction Strutinski method have been used. The weak sensitivness to nonaxial deformation has been found for even neighbours of these nuclei. The small tendency towards prolate deformation of the ground and excited one-quasiparticle states originating from the g9/2 proton subshell in 1~176 odd isotopes has been noticed. The behaviour with quadrupole e and hexadecapole e~ deformation of the ground and two-quasiparticle excited 0 + states originating from the ds/2, g9/2 and g7/2 proton subshclls and h11/2 neutron subshell in 112--118Sn has been investigated. The small quadrupole deformation of the excited 0 + states has been found what is in agreement with the experimental data concerning the rotational bands build on the first excited 0 + states in Sn isotopes.
