摘要：

In recent experimental work, the integrated ionization cross section for positron impact on atomic hydrogen has been obtained in the energy range from threshold to several hundred electron volts. All previous theoretical calculations for this process are found to lie well below the measured values. Within the framework of the distorted-wave approximation, we consider improvements to the description of the interaction between the two outgoing particles. This interaction is described in terms of effective charges while distortion in the incident channel is also included. Good agreement is obtained with experiment.
