反冲质子
Using gridded ionization chamber, energy spectrum of recoil proton was obtained in the measurement of ( n, p) reaction, and corrected using Monte Carlo method.
在测量快中子(n,p)反应的实验中,同样利用屏栅电离室测得聚乙烯薄膜反冲质子的能谱,并利用蒙特-卡罗方法对其进行校正,从而得到中子的绝对注量率。
Counting rates of the BF3 long neutron counter and the liquid scintillation detector were simultaneously increased by a factor of 15 compared to the background. A recoil proton energy spectrum of 2.45 MeV neutrons was also measured by the liquid scintillation detector with n-γ discrimination.
长中子计数器和液体闪烁计数器的计数均比本底高15倍,液体闪烁计数器同时记录了2.45MeV中子的反冲质子能谱。
