Abstract

The measurement of two-dimensional photoelectron spectrum was analyzed to study the autoionization and predissociation dynamics of superexicited HI. Investigations show the autoionization due to the 5 dπHI^*(R _A) state over a wide photon energy range. The autoionizing I ^*[R(³P_0,1)] fragments were produced by the conversions of higher-n HI^*(R_A) states into HI ^*[R(⁴II_1/2)]. The results show that potential barriers were created only on the adiabatic potential energy curve of HI ^*(R_A).
