变形核的电荷密度分布

CHARGE DENSITY DISTRIBUTIONS OF DEFORMED NUCLEI

本文应用原子核的宏观模型提出了一种比较简单的计算变形核电荷密度的方法.具体计算了_(76)^(192)Os、_(64)^(154)Gd、_(62)^(152)Sm、_(70)^(174)Yb及_(62)^(144,148,150,152)Sm等原子核的电荷密度分布.结果表明,宏观模型计算的结果能较好地与实验测量结果相符合.因此,只要根据变形核基态到各转动态跃迁几率或电多极矩的实验值,则可按本文方法,从理论上预言变形核的电荷密度分布.

A simple calculation method for charge density distributions of deformed nuclei by using macroscopic model has been proposed. The calculations of charge density distributions for ^(192)Os,^(154)Gd,^(152)Sm, ^(174)Yb and ^(144,148,150,152)Sm nuclei have been performed. The results show that the calculated charge densities are in good agreement with experiments. Consequently, on the base of experimental data of the transition probabilities for ground state to 2^+, 4^+, 6^+ rotational states or its electric multipole moments, The charge density distributions of deformed nuclei can be predicted theoretically by this method.
