Abstract

On irradiation of metallic targets from niobium and tantalum with excimer XeCl laser (308 nm) the spectra of erosion plume were obtained. These spectra were used in studying the plume qualitative composition. The velocities of atom and ion scatter were measured by the time-of-flight method. Plasma electron temperature was found by continuous spectrum of plume radiation. The results obtained were compared with the outcomes of the previously performed probe measurements of electron temperature and ion scatter velocities.
