2玻色子-费米子相互作用模型中奇质量W同位素的描述

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

S. Abu Musleh, O. Scholten

摘要:

在相互作用玻色子-费米子近似(IBFA)模型框架下研究了钨的奇偶同位素183、185、187 W的负宇称和正宇称低自旋态。耦合到玻色子系统的费米子被取为负宇称2f_7| 2,2f_5\2,3p_3\2,3p_1\2和正宇称1i_13\2单粒子轨道。计算的奇同位素低自旋能级能量与实验值符合得很好。此外,B(E2)值和光谱因子的单中子转移的计算和发现与实验数据符合得很好。

英文摘要:

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.
