摘要
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。将其结果与２３８Ｕ测得的结果进行比较，二者在误差范围内相同，说明用此方法测量中子绝对注量率是可行的。
Using gridded ionization chamber, energy spectrum of recoil proton was obtained in the measurement of (n,p) reaction, and corrected using Monte Carlo method. By this means, the absolute neutron flux was obtained and compared with the result of 238 U. They are in good agreement each with other in the error range. The result indicates that the method,using polythene film in the measurement of absolute neutron flux, is practicable.
