Abstract

This article presents a detailed study of the photodissociation probability of D_{2}^{+} for a wide range of photon energy. One dimensional numerical calculations have been performed to provide the best possible physical quantities that characterize the vibrational trapping or bond hardening effect during the photodissociation dynamics. These results undoubtedly show that the nodes of the nuclear vibrational wave packets play a decisive role in the vibrational trapping, in addition to the current understating of this phenomenon.
