[en] An anomalously narrow TL glow peak and a differential scanning calorimetry (DSC) peak due to release of stored energy were investigated in crystalline NaCl after intense electron irradiation around room temperature. A numerical calculation of the glow peak shape was carried out using rate equations with activation energies perturbed by releasing stored energy in order to explain the anomaly. A good fit of the calculated curve with the observed one reveals that the releasing of stored energy may induce strong effects on the TL process in NaCl irradiated with a high dose of electrons.
