Formation of H${}_3^{-}$ by radiative association of H${}_2$ and H${}^{-}$ in the interstellar medium

M. Ayouz, Raphael Lopes, Maurice Raoult +2

We develop the theory of radiative association of an atom and a diatomic molecule within a close-coupling framework. We apply it to the formation of H${}_3^{-}$ after the low energy co…
