Energy distribution of laser plasma neutral atoms

The experimental installation, techniques and investigation results on neutral component of laser plasma using electron impact ionization are described. For ionization the separate laser source electrons and electrons of plasma under investigation have been used. Distributions of Pb atoms have been obtained in the energy range from 10 to 200 eV for laser radiation fluxes of ranging from 2x107 to 8x109 W/cm2. It has been experimentally established that for low values of q energy distributions of atoms have thermal character and with increasing q recombinative atoms appear in the spectrum
