The results of new measurements of NaCl thermo luminescence parameters are reported. Such measurements were carried out by means of the new apparatus already described in a previous Techn. Note. The results obtained consist of the new value of the activation energy, which is confirmed as being common for all the glow peaks above room temperature and which amounts to E 1. 25 eV besides, in the new values for the probability factors p sub i, which come out to be strongly increased as compared to former measurements. Using these new values of E and of the p sub is, the Authors repeated the calculations relative to the isothermal bleaching of F-Centers, obtaining results which are not notably different from those reported in a previous Techn. Note. In a different temperature range an optical re-excitation effect of glow peaks similar to that observed by other authors at low temperature has been observed.
