Abstract

Cryogenic NO2 films were ablated by a XeCl excimer laser. Only NO2 molecules were detected by a time-of-flight method. Velocity distribution of ablated NO2 molecules was found to be almost thermal. The derived temperature of the fitted Maxwell-Boltzmann distributions depended on the thickness of cryogenic NO2 film in the range from 300 K to 1100 K. The fastest NO2 observed in the present experiment had a translational energy of 0.5 eV.
