Abstract
Metastable states population distributions of gadolinium atoms under high-rate electron beam evaporation were measured by laser light absorption. The experiments were carried out under high atomic density of 10{sup 12} {approx} 10{sup 13} atoms/cm{sup 3} at the light absorption zone and following several vapor characteristics were found: (1) The atomic excitation temperature derived from metastable states population distribution was considerably lower than the evaporation surface temperature and decreased with increasing the evaporation rate. (2) Atomic vapor is almost free from the cluster formation caused by a rapid expansion into a high vacuum. (3) The atomic density is in reciprocal proportion to the square of the distance from the evaporation surface. (author).
