Low-spin states of odd-mass xenon isotopes

摘要

In this work, we analyse the positive parity of states of odd-mass nucleus within the framework of interacting boson-fermion model. The result of an IBFM-1 multilevel calculation with the 2d5/2, 1g7/2, 3s1/2, 2d3/2 and 1h11/2, single particle orbits is reported for the positive parity states of the odd-mass nucleus 125-129Xe. Also, an IBM- 1 calculation is presented for the low-lying states in the even-even 124-128Xe core nucleus. The energy levels and e??μ(e???2) transition probabilities were calculated and compared with the experimental data. It was found that the calculated positive parity low-spin state energy spectra of the odd-mass 125-129Xe isotopes agree quite well with the experimental data.
