AbstractThe formation of the deuterated hydrogen molecule HD by the radiative association of H and D is investigated. Spontaneous association and stimulated association in a blackbody radiation field are considered. For a collision temperature of 1000 K, the rate coefficient for spontaneous radiative association is 1.0 x 10(-26) cm(3) s(-1). At the same collision temperature, the rate coefficient is enhanced by stimulated association to 1.8 x 10(-26) cm(3) s(-1) for a radiation temperature of 10,000 K. The role of radiative association in the deuterium chemistry of the early universe is discussed.
