| 摘 要： | 本文介绍了用吸收法与能谱法相结合,测定低能γ射线在物质中的光电吸收系数和康普顿散射系数。我们选用~(133)Ba放射源,(?)铜、铁、铝作吸收片,利用单道脉冲幅度分析器和函数记录仪分别测出各种实验条件下的γ能谐,得到不同的A和B值,从而计算出上面所说的两种吸收系数。

| Abstract: | The method of measured photoelectric absorption coefficient and compton scattering coefficient of the low energy gamma rays in substance is deseribed by means of absorption and energy spectrum method in this paper.
We use ~(133)Ba as radiant, using copper, Fe, aluminium as absorbent piece, gamma energy spectrum in the different experiment conditions is measured by pulse amplitude analyser and function recording meier. Then we obtain the magnitude of different A and B, and finally, the two absorption constant are calculated. |
