29—1100keV能区^(75)As中子俘获截面测量

Measurement of neutron capture cross section of ^(75)As in the energy range from 29 to 1100 keV

用活化法相对于Au的中子俘获截面 ,测量了 2 9— 110 0keV能区75As(n ,γ) 76 As的反应截面 ,测量精度为 6 .7— 7.8% ,并将测量结果与现有的实验数据作了比较。

The cross sections for the 75 As(n,γ) 76 As reaction were measured relatively to that of 197 Au in neutron energy range from 29 to 1100 keV, using the activation technique. The accuracy of the measurement was 6.7-7.8%. The experiment results were compared with existing data.
