Nuclear structure, OXBASH code, Three-body forces, Tin regionAbstract
Nowadays, the role of three-nucleon forces in the description of nuclear
structure properties is a main topic in the field of microscopic many-nucleon
calculations. Our work have been focused on the study of the spectroscopic properties
of the even-even isobars around 132Sn region. Based on the Schrödinger equation, the
calculations are carried out by means of OXBASH nuclear structure code in taking into
account the three-body forces interaction. After some modifications, a new interaction is
derived from kh5082 empirical interaction. The energies of the low-lying states of these
isobars have been determined. The obtained results have compared with available
experimental data.
