Abstract
Photoionization quantum yields of organic molecules in liquid argon and xenon have been measured. The liquid rare gases are excited by α particles, and vacuum ultraviolet photons emitted from the respective excimer ionize the organic molecules. The quantum yields for TMA (trimethylamine) and TEA (triethylamine) in liquid xenon are observed to be as large as 80% in contrast to much smaller values in the gases in the same excess energy region.Keywords
