Abstract
The enhancement of the rate coefficient for the radiative association of He and H+ to form HeH+ arising from stimulated emission due to a blackbody ra diation held is calculated. The effects on the fractional abundance of HeH in the early universe, in supernova ejecta, and in planetary nebulae are s mall. There may occur some enhancement in the abundance of HeH+ in quasar b road-line clouds.
