EQUIVALENCE OF THE KOBRAK-RICE PHOTOSELECTIVE ADIABATIC PASSAGE AND THE BRUMER-SHAPIRO STRONG-FIELD METHODS FOR CONTROL OF PRODUCT FORMATION IN A REACTION

It is shown that the photoselective adiabatic passage approach to cont rol of product formation in a chemical reaction proposed by Kobrak and Rice may be viewed as a high-field limit of the strong field Brumer-S hapiro scheme. It is further shown that the adiabatic passage represen tation provides new insight into the nature of control over chemical r eactions in strong fields, and that it correctly predicts the results of physically realistic simulations of the sodium dimer.
