A description of odd mass Xe and Te isotopes in the Interacting Boson-Fermion Model

TL;DR

This paper models odd-mass Xe and Te isotopes using the Interacting Boson-Fermion Model, successfully reproducing low-spin energy levels and transfer reaction data, providing insights into their nuclear structure.

Contribution

It applies the Interacting Boson-Fermion Model to odd Xe and Te isotopes, including multiple single-particle orbits, and compares calculated results with experimental data.

Findings

Calculated energy levels agree well with experiments

B(E2) and B(M1) transition rates match observed values

Spectroscopic factors for neutron transfer are accurately reproduced

Abstract

Recent interest in spectroscopic factors for single-neutron transfer in low-spin states of the even-odd Xenon $^{125,127,129.131}$Xe and even-odd Tellurium, $^{123,125,127,129,131}$Te isotopes stimulated us to study these isotopes within the frame work of the Interacting Boson-Fermion Model. The fermion that is coupled to the system of bosons is taken to be in the positive parity $3s_{1/2}$, $2d_{3/2}$, $2d_{5/2}$, $1g_{7/2}$ and in the negative $1h_{11/2}$ single-particle orbits, the complete 50-82 major shell. The calculated energies of low-spin energy levels of the odd isotopes are found to agree well with the experimental data. Also B(E2), B(M1) values and spectroscopic factors for single-neutron transfer are calculated and compared with experimental data.
