摘要：

The photoionization efficiency spectrum of supersonically cooled CS in the region of 1000-1100 angstrom is presented. The CS transient molecules are prepared by 193 nm photodissociation of a pulsed supersonic CS2 free jet. The ionization energy for CS is determined to be 11.318 +/- 0.007 eV. The observed PIE spectrum for CS and that for SO from the 193 nm photodissociation of a SO2 free jet support the conclusion that rotational and vibrational excitations of photofragments relax efficiently in the supersonic expansion.
