Abstract

Population distributions of metastable state of gadolinium atoms produced by electron beam heating were measured by laser light absorption. The atomic excitation temperature was determined to be 14001600 K from the population distributions. The atomic excitation temperature decreased with increasing evaporation and was much lower than the evaporation surface temperature of 21002400 K which was estimated from, the evaporation rate.
