摘要： 为研究在中子-核散射中存在的以GR (巨共振)为中间态的反应机制,本文测量了满壳缺一个中子的87Sr (n,n')87mSr (En<3.4MeV)的非弹散射截面.由En=0.68MeV及En=3.28MeV的单一激发((9+)/2→(1-)/2)截面值,定出了((9+)/2→(1-)/2)的激发曲线的趋势.经与理论计算比较,进一步证实在核子-核散射中可能存在着一种以巨共振态作为中间态的反应机制.

Abstract: The theoricians[1] have found that the virtual excitation of GR plays an important role in 87Sr(n, n')87mSr inelastic scattering, the target with a hole in a neutron close shell, even when the incident neutron energy is around 3 MeV. The cross section of 87Sr (n, n')87mSr((9+)/2→(1-)/2) has been calculated for compound nucleus'with H-F formula, for GR'S with phenomenological as well as microscopical method, hut there are no experimental data that could compare with them directly yet.
