Multiphoton Dissociation of HeH+ below the He+(1s) + H(1s) Threshold
Abstract
We discuss the strong-field dynamics of HeH+, the simplest stable heteronuclear molecule, focusing on identifying a laser regime for which there is a sufficient dissociation signal for experimental measurement. We numerically solve the time-dependent Schr\"odinger equation to obtain total dissociation probabilities, kinetic energy release spectra, and momentum distributions for wavelengths from 800 nm to 2400 nm. The suitability of this simple system as a prototype for understanding the strong-field nuclear dynamics of heteronuclear dissociation is discussed.
