摘要
在平面波玻恩近似(PWBA)中研究了19O和21Na奇异原子核的横向磁电子散射形式因子。对基态和低洼激发态进行了三种 sd 壳相互作用(USDA、USDB 和 Wildenthal)的壳模型计算。通过平移不变壳模型(TISM)对玻恩近似图进行了精确的质心校正,以修正横向形式因子。测量到的磁偶极矩与通过有效 g 因子引入的磁芯极化效应(CP)很好地重现了。此外,还计算了价核子的占位百分比。
Role of the Center of Mass Correction in Magnetic Form Factors for 19O and 21Na Exotic Nuclei with Different Interactions
The transverse magnetic electron scattering form factors of 19O and 21Na exotic nuclei were studied in the plane wave Born approximation (PWBA). The shell model calculations with three sd-shell interactions, USDA, USDB, and Wildenthal, were carried out for the ground and low-lying excited states. The exact center of mass correction in the Born approximation picture through the translation-invariant shell model (TISM) was included to modify the transverse form factors. The measured magnetic dipole moments were well reproduced with the core polarization (CP) effect introduced through the effective g-factors. The occupancies percentage with respect to the valence nucleons was also calculated.
