The isospin admixture of the ground state and the properties of the isobar analog resonances in deformed nuclei

Abstract

Within quasiparticle random phase approximation (QRPA), Pyatov-Salamov method for the self-consistent determination of the isovector effective interaction strength parameter, restoring a broken isotopic symmetry for the nuclear part of the Hamiltonian, is used. The isospin admixtures in the ground state of the parent nucleus, and the isospin structure of the isobar analog resonance (IAR) state are investigated by including the pairing correlations between nucleons for 72-80Kr isotopes. Our results are compared with the spherical case and with other theoretical results
