标题： Spin-dependent observables in surrogate reactions

摘要： 从复合核的不同自旋态发出的可观测量被研究，以验证替代反应方法的有用性。 发现级联$\gamma$-射线的能量谱及其多重性、蒸发中子的谱以及裂变碎片的质量分布明显依赖于衰变核的自旋。 目前的结果表明，它们可用于推断占据的自旋分布，这些分布显著影响由替代反应产生的复合系统的衰变分支比。 显示英文摘要

摘要： Observables emitted from various spin states in compound U nuclei are investigated to validate usefulness of the surrogate reaction method. It was found that energy spectrum of cascading $\gamma$-rays and their multiplicities, spectrum of evaporated neutrons, and mass-distribution of fission fragments show clear dependence on the spin of decaying nuclei. The present results indicate that they can be used to infer populated spin distributions which significantly affect the decay branching ratio of the compound system produced by the surrogate reactions.
