Abstract

To measure the total neutron cross sections, the authors developed a convenient technique using silicon semiconductor detectors with the simple and compact detecting system. The created technique was used to measure A + n total cross sections at the energy E_n = 14.1 MeV for several nuclei in different mass region. The neutron generator NG-150 in D + T regime of neutrons generation is used as fast neutrons source. The results of measurements and their comparison with the appropriate literature values are also presented.

摘要

为了测量中子的总截面，作者开发了一种使用硅半导体探测器的简便技术，该探测器具有简单而紧凑的探测系统。对于能量在不同质量区域中的多个原子核，所创建的技术用于在能量E _n = 14.1 MeV下测量A + n总横截面。处于中子产生D + T态的中子发生器NG-150被用作快速中子源。还介绍了测量结果及其与适当文献值的比较。
