We have analyzed the photoionization of Cr2+ in InP by the Deep Level Optical Spectroscopy (D.L.O.S.). The σ°n cross section exhibits both a resonant and non resonant character. The former corresponds to the internal transition 5T2-5E of Cr2+ while the threshold of the second allows us to locate the Cr2+/Cr3+ level below the conduction band. The absolute photoionization cross sections towards the two bands are very similar. In particular no selection rule seems to work.
