摘要

对 10B 核的四种态的非弹性横向电子散射形式因子进行了研究。这些状态分别是J T  =1+0 (0.718 MeV)、1 0 2 (2.154 MeV)、2+0 (3.587 MeV)和3 0 2 (4.774MeV)。横向形式因子是在多核配置混合壳模型的框架内利用科恩和库拉特(C-K)的两体相互作用产生 1p 壳波函数计算出来的。计算中通过有效的 g 因子包含了核极化(CP)效应。1p 壳模型空间之外的高配置效应增强了 q 值的形式因子,并合理地再现了数据。选择尺寸参数(b)的值是为了再现均方根电荷半径。本结果与现有实验数据和其他模型的结果进行了比较。PACS:21.60-n,21.60 Cs, 25.30Dh,27.20 th

STUDYING INELASTIC TRANSVERSE ELECTRON SCATTERING FORM FACTORS OF THE ISOSCALAR TRANSITIONS IN 10B NUCLEUS
The inelastic transverse electron scattering form factors are studied for the fourisoscalar transitions for the states of 10B nucleus. These states are specifiedby J T  =1+0 (0.718 MeV), 1 0 2 (2.154 MeV), 2+0 (3.587 MeV) and 3 0 2 (4.774MeV). These form factors are analyzed in the framework of the harmonic oscillatorshell model.The transverse form factors have been calculated in the framework of the multinucleonconfiguration mixing shell model using the two-body interaction of Cohenand Kurath (C-K) to generate the 1p-shell wave function. The core polarization (CP)effects are included in the calculations through effective g-factors. A higherconfiguration effect outside the 1p-shell model space enhances the form factors forq-values and reasonably reproduces the data. The value of the size parameter (b) ischosen to reproduce the root mean square charge radius. The present results arecompared with available experimental data and with that of other models.PACS:21.60-n,21.60 Cs, 25.30Dh,27.20 th
