^（152）Sm的22－1019keV能区中子俘获截面的测量

Measurement of neutron capture cross-section for ￣(152)Sm in energy range of 22-1019keV

在４．５ＭｅＶ静电加速器上．利用７Ｌｉ（ｐ，ｎ）７Ｂｅ和Ｔ（ｐ．ｎ）３Ｈｅ反应作为中子源，在２２－１０１９ｋｅＶ中子能区以（１９７）Ａｕ的中子俘获截面为标准，用活化法测量了（１５２）Ｓｍ的中子俘获截面．其误差小于６．８％。

The cross-sections for 152Sm(n, γ )153Sm reaction in the neutron energy range of 22- 1019keV are obtained from the neutron capture cross-section data for 197Au by the activation method, with an error of less than 6.8%.
