摘要
Integral cross sections for the reaction He + H-2+ --> HeH+ + H have been computed with the hyperspherical method in the threshold energy range. The ab initio potential of McLaughlin and Thompson, fitted by Joseph and Sathyamurthy, has been used. A lifetime matrix analysis of the J = 0 reaction probabilities shows the existence of many long-lived resonances, with several having lifetimes as long as 3.1 ps. The magnitude of the local reaction cross section is in reasonably good agreement with the experimental result of Chupka (1968).
