Nature of the additional delay of prompt radioluminescence photon emissionin organic solids and its description by Gauss function

In contrast to photoluminescence kinetics of organic solid materials for ra dioluminescence one an additional delay of the moments of photon emission i s observed. We have carried out the detailed physical ground of application of Gauss function for description of this delay. The precise analysis of t he experimental results let us the possibility to prove the plural nature o f the processes causing formation of the radioluminescence pulse.
