摘要

研究了235U的热中子裂变生成53.3-d 7Be和280-yr 32Si。7Be和32Si的裂变产率分别为2·10−10%和1.2·10−10%。这些同位素的产率比仪器测量结果显示的要低4到5个数量级。

Search for 7Be and 32Si as products of ternary fission of 235U by thermal neutrons

The yields of 53.3-d ⁷Be and 280-yr ³²Si from the thermal-neutron fission of ²³⁵U have been investigated. Upper limits of 2 · 10⁻¹⁰% and 1.2 · 10⁻¹⁰% have been set for the fission yields of ⁷Be and ³²Si, respectively. The yields of these isotopes are lower by 4 to 5 orders of magnitude than indicated from results of instrumental measurements.
