Abstract

Elastic and inelastic electron scattering form factors for the 17 O nucleus are calculated for the positive parity low-lying states in the momentum transfer interval 0.05-3 fm − 1 in the framework of shell model and Skyrme-Hartree-Fock calculations. Also, protons, neutrons, mass and charges root mean square, r.m.s., radii and the charge spatial density distribution are calculated. The ZBME model space out of 12 C nuclei core with rewile interaction have been used. For all selected ground and excited states, Skyrme interactions with SkXcsb and SLy4 parameter, harmonic and Wood-Saxon potentials are adopted in Hartree-Fock theory to generate the mean potential and hence calculate the elements of single-particle matrix and form factors. Also, we have used Tassie model to account for core-polarization effect. Finally, to check the reality
用Skyrme-Hartree-Fock方法研究17O核的正宇称态形成因子
在壳层模型和Skyrme-Hartree-Fock计算的框架下,计算了17 O核在动量传递区间0.05 ~ 3 fm−1的正奇偶位低空态的弹性和非弹性电子散射形因子。计算了质子、中子、质量和电荷的均方根、均方根、半径和电荷的空间密度分布。采用了12c核外的ZBME模型空间,并进行了二次相互作用。对于所有选定的基态和激发态,在Hartree-Fock理论中采用Skyrme与SkXcsb和sl4参数、调和势和Wood-Saxon势的相互作用产生平均势,从而计算出单粒子矩阵的元素和形状因子。此外,我们还使用了Tassie模型来解释核心极化效应。最后,检查一下现实
