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

Recent interest in spectroscopic factors for single-neutron transfer in low-spin states of the even-odd Xenon 125,127,129.131Xe and even-odd Tellurium, 123,125,127,129,131Te isotopes stimulated us to study these isotopes within the framework of the Interacting Boson-Fermion Model. The fermion that is coupled to the system of bosons is taken to be in the positive parity 3s1/2, 2d3/2, 2d5/2, 1g7/2 and in the negative 1h11/2 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.
