heal.abstract	The applicability of the thermionic model for exoelectron emission was examined on a thin film (0.1 mum) of KCl by measuring the activation energies for exoelectron emission (0.73 +/- 0.02 eV) and thermoluminescence (0.64 +/- 0.02 eV) and the electron affinity (0.70 +/- 0.08 eV) of the solid. The electron affinity was measured through the study of the energy distribution of the secondary electrons. The exoelectron emission was found to be strongly correlated with thermoluminescence. In the temperature interval of -60 to 120 degreesC, in which the peaks in both phenomena were exhibited, no variation of the value of the electron affinity was observed, while its coefficient of temperature variation was found to be less than 7 x 10(-4) eV K-1. The irradiation of the film with 600 eV electrons did not affect the electron affinity, even at the level of 2.5 x 10(13) electrons cm(-2), a fluence (total number of particles per unit area) which was found to cause fatigue of the material as far as the two phenomena were concerned.	en
