摘要
用与半经典交换势（ＳＣＥ）不同的三种交换势计算了低能ｅ－Ｈｅ弹性散射的相移，结果表明，这三种势均在不同程度上改善了ＳＣＥ势的结果．
Phase shifts for elastic scattering of electrons from helium in low energy region are calculated by use of three exchange potentials that are different from semiclassical exchange potential.The results is better than those by SCE.
