The purpose of the paper is to report the optical absorption and thermoluminescence measurements on KCl: Ba 2+ crystal irradiated with γ‐rays. Bleaching in F‐band increases the glow peak around 75 °C and suppresses the 125 °C peak. A similar result is observed in preheat treated crystals. When this peak is thermally cleaned, the broadening of the absorption on the prolonged F‐bleached crystals is removed. On the basis of these observations, the glow peak at 75 °C is tentatively attributed to Z 1 ‐centers.
