Abstract
We have studied the Stark effect on high singlet Rydberg states of para-H[sub 2] which converge to the [ital v][sup +]=0, [ital N][sup +]=0,2 ionization limits using multiphoton excitation and ionization, through monitoring the predissociative decay channel. We observe the formation of hydrogenic Stark manifolds with increasing field, as well as the appearance of forbidden transitions and interactions between states possessing different core rotational quantum numbers. Comparison of our experimental results with a perturbation calculation suggests that the predissociation rates of the Stark components are determined primarily by the degree of admixture of [ital ns] and [ital nd] character in their wave functions. Directly field-induced predissociation of the Stark states may also play a role in their decay.
