摘要：

The author discusses impact ionisation of polarised atoms (Li, Na, K and metastable excited He) by polarised electrons. The consequences of the ‘maximum interference approximation’ in theoretical ‘distorted wave’ calculations for the total cross sections and the spin asymmetry are investigated. Numerical results obtained with the DWBA method are compared with recent experimental data. The agreement between theory and experiment is only marginal. This indicates that more sophisticated methods are needed to enable correct theoretical predictions of the spin dependent ionisation asymmetry. © 1990 IOP Publishing Ltd.
