A description of odd mass W-isotopes in the Interacting 2 Boson-Fermion Model

TL;DR

This paper models the low-spin states of odd-mass tungsten isotopes using the Interacting Boson-Fermion Approximation, successfully matching experimental energy levels, transition rates, and transfer spectroscopic factors.

Contribution

It applies the IBFA model to odd-mass tungsten isotopes, incorporating specific negative and positive parity single-particle orbits, and achieves good agreement with experimental data.

Findings

Calculated energy levels match experimental data.

B(E2) transition rates agree with measurements.

Spectroscopic factors are consistent with experiments.

Abstract

The negative and positive parity low-spin states of the even-odd Tungsten isotopes, 183,185,187W are studied in the frame work of the Interacting Boson-Fermion Approximation (IBFA) model. The fermion that is coupled to the system of bosons is taken to be in the negative parity 2f_7|2, 2f_5\2, 3p_3\2, 3p_1\2 and in the positive parity 1i_13\2 single-particle orbits. The calculated energies of low-spin energy levels of the odd isotopes are found to agree well with the experimental data. Also B(E2) values and spectroscopic factors for single-neutron transfer are calculated and found to be in good agreement with experimental data.
