摘要

发射2、3、4或5个中子的中子诱导裂变事件对裂变产率的贡献不同，用双中子和三中子符合信号记录为入射中子能量的函数。这个事实可以用来寻找裂变共振中中子多重度的变化，特别是在不同通道自旋的共振中。在235U的情况下，3 -和4 -能级的裂变中子数在实验误差±1.5%以上没有发现差异。

Neutron multiplicity measurement on resolved fission resonances of 235U

Neutron induced fission events emitting 2, 3, 4 or 5 neutrons have different contributions to fission yields recorded with double and triple neutron coincidence signals as a function of incoming neutron energy. This fact can be used to search for variations of neutron multiplicities in fission resonances, in particular in resonances of different channel spins.

In the case of ²³⁵U no difference in fission neutron numbers for 3⁻ and 4⁻ levels has been detected above the experimental error of ± 1·5 %.
