摘    要:本采用带有截断函数的极化势,为确定其中的可调参数,给出了一个经验公式:r↑-/r0=0.618。通过慢电子与亚稳态He(2^3S)弹性散射总截面的计算,表明本确定的极化势更准确地描述了慢电子与亚稳态He弹性散射的实际过程。

关 键 词:弹性散射  电子  总截面  亚稳态  极化  可调参数  函数  文采  实际  准确

Abstract:In this paper,the polarization potential with the cut-off fraction is used to calculate the total cross section of low-energy electron elastic scattering on metastable helium atom.In order to determine the adjustable parameter in the polarization potential,the empirical formula is given:Fr 0.The result indicates that the given polarization potential is more accurate than others in describing the interaction between a low-energy electron and a metastable helium atom.
Keywords:polarization potential  adjustable parameter
