广义Hylleraas三电子积分
Extended Hylleraas three-electron integral
摘要：
得到了三电子Hylleraas积分的一个粒子间坐标的二次幂倒数的封闭形式表达式，并推导了其他坐标的正幂的递推关系.这一结果适用于锂和轻类锂离子相对论效应的高精度计算。
英文摘要：
A closed form expression for the three-electron Hylleraas integral involving the inverse quadratic power of one inter-particle coordinate is obtained, and recursion relations are derived for positive powers of other coordinates. This result is suited for high precision calculations of relativistic effects in lithium and light lithium-like ions.
