Abstract : It is shown that by experimentally determining the magnitude of the kinetic coefficient of the transition from the i-th level to the L-th level, and probability of elementary radiation transition at a frequency where i>1, it is possible to evaluate the possibility of creating negative temperatures in semiconductors in a stationary regime of lighting.
