摘　　要：本文利用实测337 MeV/u^(20)Ne离子轰击厚Cu靶的出射中子能谱计算了高能重离子反应的中子屏蔽,并与用Madey理论的计算结果作了比较。两者的结果完全一致。The neutron shielding for the high energy reaction of 337 MeV/u 20Ne ions on thick Cu target is calculated with the measured neutron spectrum. Both results of concrete shielding thickness obtained from this method and from Madey's theory respectively, are completely coincident.
