摘要
利用加速器单能中子源测量了３和１４ＭｅＶ中子在厚度为０一６ｃｍ的较大铁板中的穿透率，测量表明在一定范围内中子衰减可近似用指数规律描述，指数因子低于宏观截面。测量结果与Ｍｏｎｔｅ－Ｃａｒｌｏ模拟计算大致符合。
The penetrability of 3 and 14MeV neutron passing through Fe slabs with thickness of 0一6cm is measured.The experimental resuIts can be aproximatively described by exponential func-tion in fixed range. The exponential factor is lower than macroscopic cross section and the experi-mental data are approximately in agreement with Monte-Carlo calculations.
