Dissociation of a diatomic molecule induced by discontinuous reversals of a static electric field

Abstract

ABSTRACT:A diatomic molecule modeled by a Morse oscillator is shown to undergo dissociation if the external electric field, in which the molecule is placed, undergoes discontinuous reversals. A threshold frequency of reversal is found to exist. The classical behavior is compared with its quantum counterpart. The mechanism of dissociation is analyzed.

Localization in some discontinuously and randomly driven quantum systems

“…The Morse parameter are reported in Table I In a previous communication [12], we reported the onset of dissociation of a hetero diatomic molecule in a discontinuously reversing electric field of low intensity when the fixed reversal time ( R ) exceeded a critical value c . If the time lag R between such reversals is kept fixed at R ϭ 200 a.u.…”

Quantum dynamics of a discontinuously kicked charged particle in harmonic, symmetric double, or triple wells

“…We have shown elsewhere 11 that a Morse oscillator exposed to a homogeneous but discontinuously reversing static electric field undergoes dissociation when the reversal frequency of the field $\left(\nu_{\rm R} = {1\over \tau_{\rm R}}\right)$ exceeds a threshold value. Below the critical or threshold frequency formation of different types of “quantum phase‐space” structures were noted.…”
