An exact quantum mechanical study of the isotopic collinear reactive systems H₂+ Cl and D₂+ Cl

An exact quantum mechanical study is performed on the collinear reactive systems H2 + Cl and D2 + Cl. Using a LEPS surface with a barrier height of 0·33 eV, the reactive transition probabilities were derived. Isotopic effects, threshold effects, effects of opening of new states and the influence of the initial state are considered to some extent.
