| Abstract: | The semirigid vibrating rotor target (SVRT) model is applied to study the reaction of D＋CD4→CD3＋D2 using time-dependent wave packet (TDWP) method. The energy dependence of the calculated reaction probability shows oscillatory structures, similar to those observed in the reactions H+H 2, H+CH 4 etc. Authors have also studied the influence of the reacting molecule (CD 4) on reaction probability. The excitation of the D-CD 3 stretching vibration gives significant enhancement of reaction probability. And the reaction probability rises significantly with the enhancement of rotational quantum number j . |
