Abstract

The first experiment results on investigation of molecular composition kinetics in D-T mixture depending on temperature by means of Raman spectroscopy are given. The D-T mixture is contained within the glass microspheres used as laser thermonuclear fusion (LTF) targets. It is experimentally shown that the isotope molecules concentrations do not change with rapid temperature alteration from 4 - 77 K to room temperature. Two suppositions can explain the results: either the equilibrium concentration establishment time was less 5 minutes or molecule concentration is equal to the high temperature equilibrium concentration regardless of microspheres temperature.
