The spectra of photoelectrons created by AlK α X‐rays are investigated in CsJ, CsF, LiJ, and LiF photocathodes. The energy distributions of the photoelectrons are determined by measuring the photoelectric current between two concentric spherical electrodes with a variable retarding potential between them. For a LiF target, the electron spectrum is analysed quantitatively using an analytical model for the energy distribution of the K photo and K → LL Auger electrons from fluorine atoms. A strong deviation from Whiddington's law is found for the penetration model of the electrons.
