本文提出改进经验势能函数的一般方法,即构成改进后的势能函数V=WV′,校正函数W=exp{P[(γe/γ)q-1]}。此法应用于改进Rydberg函数与PG函数,结果成功。
A general method to modify the empirical potential energy functions is proposed V(r) =W(r)V'(r) with correction function W(r) = exp{p[((rc/r)q-1]}. It has been successfully used for the modification of the Rydberg functicn and the Pseudogaussian (PG) function.
