Study of Systematic Behavior for Neutron-, Proton- and Photon-induced Fission Cross Sections at Intermediate Energy Region

利用裂变几率的简单行为，假定裂变几率的最大激发能和Z ~ 2/A依赖关系的函数形式，得到了统一描述中子、质子和光子诱发反应的裂变几率系统。在几十MeV到3GeV的能量范围内，本文的结果可以在10%的精度内描述中能区的裂变截面。

The systematics of fission probability with unified description of neutron-, protonand photon-induced reactions has been obtained by using its simple behavior as assumed a functional form which is designed to describe the maximum excitation energy and Z2/A dependences of fission probability. The present results can describe the fission cross sections in the intermediate energy region within about 10% accuracy in the energy region from several tens of MeV to 3 GeV.
