Fully quantum-mechanical calculations have been performed to determine the radiative collisional cross sections for quenching of metastable muonic hydrogen p..mu../sup -/(2s) by normal hydrogen atoms and for quenching of the metastable muonic helium ion ..cap alpha mu../sup -/(2s) by normal helium atoms. The interatomic potential curves and the radiative transition rates for the mixed electronic-muonic systems are calculated using molecular-structure methods. The nuclear motion is treated as adiabatic and the interaction is written in terms of a complex potential. The cross sections are evaluated by direct numerical integration of the Schroedinger equation. The two-body thermal (300 K) quenching rate constants obtained are 3.7 x 10/sup -13/ cm/sup 3//sec for p..mu../sup -/ and 6.0 x 10/sup -15/ cm/sup 3//sec for ..cap alpha mu../sup -/.
