White, M G; Grover, J R

The results of a systematic investigation of electronically autoionizing Rydberg states in HCl are discussed. Vibrationally resolved photoelectron spectroscopy was used to map out the non-radiative decay of vibronic levels of 3psigma ..-->.. n(/sub d//sup s/)sigma Rydberg states converging to the A/sup 2/..sigma../sup +/(3psigma)/sup -1/ excited ionic state. The observed vibrational distributions of the resulting X/sup 2/PI(1..pi..)/sup -1/ ionic state are compared with the results of model calculations of Terwilliger and Smith based on spectral analysis of the absorption spectrum. Overall, the X/sup 2/PI vibrational branching ratios are found to be in only rough qualitative agreement with the calculations and these results are discussed in relation to the approximations involved. 18 refs., 4 figs., 1 tab.
