摘要
The negative and positive parity low-spin states of the even odd Tungsten isotopes, W-183.185,W-187 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. (C) 2012 Elsevier B.V. All rights reserved.
