摘要：

The rate of the radiative decay of the HeH+(b (3) Sigma(+)) molecular ion has been investigated. At infinite internuclear separation the b (3) Sigma(+) electronic state dissociates to form metastable atomic helium He(2 S-3) and a proton H+. The optically allowed electronic transition to the lowest triplet HeH+(a (3) Sigma(+)) state which dissociates to He+(1s) and H(1s) was considered. This transition can lead to the population of metastable triplet (a (3) Sigma(+)) states in beams of HeH+ ions.
