Key Points

The study determines the energies of low-lying states of even-even isobars, identifying improvements due to three-nucleon forces.
Calculations utilize the Schrödinger equation and OXBASH code, resulting in a modified interaction from kh5082 to enhance accuracy.
Comparative analysis shows how the derived results align with existing experimental data, validating the effectiveness of the new interaction.
Through the use of three-body forces, this work could reshape understanding of nuclear structure properties in the 132Sn region.

Abstract

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.
