The absorption in F‐band of NaCl single crystals after X‐ray irradiation and later excited with laser light is studied. Similar investigations have been carried out when these crystals are subjected to high AC electric fields prior to X‐ray irradiation and also at elevated temperatures. Effect of laser excitation on γ‐ray irradiated samples is studied. An attempt is made to understand the results in terms of the disorder that sets in in these crystals.
