Resonances at very low temperature for the reaction D${}_2$+H

Abstract

We present numerical results for rate coefficients of reaction and vibrational quenching in the collision of H with D${}_2(v,j)$ at cold and ultracold temperatures. We explore both ortho-D${}_2(j=0)$ and para-D${}_2(j=1)$ for several initial vibrational states $(v\le 5)$, and find resonant structures in the energy range 0.01--10 kelvin, which are sensitive to the initial rovibrational state $(v,j)$. We compare the reaction rates for D${}_2$+H with our previously obtained results for the isotopologue reaction H${}_2$+D, and discuss the implications of our detailed study of this benchmark system for ultracold chemistry.
