摘要：
A study was carried out, focusing on a two-electron transition process in an e+-He atom system where two competing processes occur simultaneously: the formation of Ps and the ejection of another electron. The correlation effect in both the channels was accounted. Results of this study corroborate the experimental findings that in the double ionization (DI), the Ps channel is strongly suppressed in the second ore gap region for some noble gases where TI is the only open channel for the DI process of the target atom.
