摘要：

Some TL glow peaks appear in corundum crystals subjected to ionizing irradiation. The highest temperature TL peak at about 600 K, is due to chromium impurity. The non-chromium TL peaks are suppressed at an increase of chromium concentration. They disappear completely at a sufficiently low chromium concentration because of an anomalous big capture cross-section of charge carriers by chromium ions. The free charge carriers capture radius was estimated from dependence of TL intensity of non-chromium TL glow-peaks on the chromium concentration. It was equal to 4.2 nm.
