Study of the processes of uranium oxides formation from uranate compounds under the effect of double laser pulses

Spectroscopic analysis of the near-surface laser plasma emerging close to a surface of the cellular body which is affected by serial double powerful laser pulses and contains micro quantities of sodium and ammonium polyuranates has been conducted. As a result, it is shown that the intensity of uranium lines in spectra is proportional to the component amount in plasma and it depends essentially on the physicochemical properties of uranium compounds. It is revealed that the line intensity increases several times with practically the same gain of the enthalpy of compounds formation. Requirements of the influence of laser parameters and processes in plasma and cellular body volume over the formation of certain ionic, atomic and molecular structure of plasma and uranium oxides in the cellular body have been defined.
