Diagnostics of recombinating laser plasma by the thomson scattering method and calculations of populations of excited states of ions

The aim is to develop the technique of diagnostics of scattering laser plasma, to measure values of plasma density and temperature at different distances from the target, to study regularities of changing plasma parameters during scattering, as well as recombination processes in plasma. Numerical calculations of hydrogen-like ion states populations in laser plasma are given. It is shown that three-particle recombination is a dominant recombination process in laser plasma at distances of 1 cm from the target. The method of laser plasma diagnostics is developed based on the Thomson scattering phenomenon, local values of electronic density and temperature of laser plasma are first measured, regularities of their change during scattering at distances of 1 cm are determined. The results received can be used at a number of scientific centers.
