Dissociation and dynamics of the high-vibrational-state HF molecules under intense half-cycle and few-cycle pulses

Abstract

This work explores the dissociation dynamics and angular distribution of the HF molecule interacting with intense half-cycle and few-cycle pulses, including the rotational degree of freedom. The dependences of the dissociation probability on both the pulse type and the pulse duration are discussed. Our results indicate that the angular distribution of the dissociation probability is highly asymmetric to the perpendicular direction of field polarization, and becomes more symmetric with an increase in the number of field cycles. The spatial distribution of the wave function demonstrates the feasibility of constructing a molecular wave packer by interacting with the half-cycle pulse.
