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 die 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 Kr72-80 isotopes. Our results are compared with the spherical case and with other theoretical results.
