简介：流行乐队组合“原子猫”由纳塔莎·汉密尔顿、珍妮．弗罗斯特和利兹·麦克拉农组成，人们常称她们为塔什、珍妮和利兹。凯芮·卡托纳是“原子猫”发起人之一。但为了做全职妈妈，她离开了乐队，2001年1月，珍妮·弗罗斯特接替了她的位置。

简介：原子的电的偶极子polarizabilities在许多不同物理应用是很重要的，例如精确原子频率标准。这些性质的计算很重要、挑战性。我们建议计算策略由使用电子关联能足够地被考虑的一套高质量的轨道的底变化地与高精确计算频率依赖者偶极子polarizabilities。Na的扎根的状态的静态的polarizabilities被如此的一个方法精确地计算并且能直接与精确实验测量相比。计算结果在对在大约0.1%以内的可得到的试验性的大小的优秀同意，它表明我们的策略的有效性。我们的计算策略有一个宽用法，不是仅仅在polarizibilies，而且在象散布的电子原子的理论处理那样的另外的地里处理。用一样的轨道的底，我们执行Na的精确计算[?]亲密关系。我们的计算亲密关系在对在0.1%以内的精确激光光谱学大小的优秀同意。[从作者抽象]
