摘要：

Positron-atom inelastic processes are formulated in terms of the random phase approximation (RPA). The theory is applied to the excitation of both the 2 1S and 2 1P levels of He. The experimental values of the literature, attributed to excitation to the 2 1S level, are shown to be in excellent agreement with theoretical values for transition to the 2 1P state. © 1990 IOP Publishing Ltd.
