摘要
在电子和激发态原子散射的物理过程中,靶的连续态是非常重要的通道,我们使用等价局部光学势模型计算了从电离阈值到200eV能量范围的氦的23S亚稳态的电离截面,并同实验结果作了比较。
arget continuum is very important channel in electron scattering by excited atoms. The total ionization cross sections for electron impact on the metastable helium are calculated by using an equivalent-local optical potential model from the ionization threshold of 23S metastable state of helium to 200eV and compared with experimental measurement.
