Die kristallisationsgeschwindigkeit des bestrahlten glasigen selens

At the temperature of 90°C the crystallization rate of γ-irradiated (0–154.5 Mrad) vitreous selenium has been studied by the calorimetric method. The obtained results satisfy the Avrami's equation x = 1 ? exp(? L·C_Kr·τ^z). It was found that radiation induced changes of vitreous selenium structure bring about the decrease of the exponent z and the increase of the value L·c_Kr.The relationship between the above results and structural changes of vitreous selenium was discussed.
