Abstract

Photoionization thresholds of Sin (n=2-40) were examined by vacuum UV radiation (5.7-8.5 eV) generated by stimulated Raman scattering of narrow-bandwidth 193-nm radiation in high pressure hydrogen and deuterium gases. A strong threshold energy dependence on cluster size is observed, featuring major maxima at 10 and 20. The magic behavior at n=10 is consistent with the results of the photofragmentation and CID experiments reported previously.
