阈能 [
yù néng]
[核] threshold energy
- 为满足核工程对核数据的需求,基于铜及其同位素阈能从99。
To meet the needs for nuclear data, the evaluation of neutron data and covariance data for ~(65, 63, Nat)Cu in the energy range from 99. - 主要用于研究非稳定核素的结构、核天体物理中相关核的阈能共振态的能级参数测量等。
This method is mainly used in the investigation of unstable nuclei and the level parameters measurement of near threshold resonant state of the nuclear astrophysics related nuclei. - 研究了核内△N→NN散射截面的介质效应,发现阈能附近的△吸收截面在介质中被压低。
The medium effects on the △N→ NN cross section is investigated, and it is found that the effective cross sation is suppressed in the medium near the threshold energy.
