It has been observed that the photoconductivity spectrum of Te-doped GaP has sharp photocurrent peak at the position of the C-line (due to the radiative recombination of an exciton bound to a neutral donor) at 4.2 K and 1.8 K. This observation was performed by using the tunable wavelength pulsed laser as a source of the excitation. This gives a direct evidence for the non-radiative Auger process of the bound exciton annihilation. The probability of the Auger process is estimated from this experiment.
