论文摘要
我们研究了超颈us $_λ^4 $ he中最终状态相互作用在非中性弱衰减$λn\ rightarrow nn $（n是中子，n是中子或质子）中的效果。使用三体模型，考虑了发射核子对与残留核的相互作用的变形的影响。我们还使用Migdal-Watson模型研究了发射核子之间最终状态相互作用的影响。还考虑了旋转对称性在两对的最终状态下的影响。根据我们的计算，我们得出结论，最终状态相互作用在发射核子对的动能谱中起较小的作用。
We study the effects of final state interactions in the non-mesonic weak decay $ΛN \rightarrow nN$ (n is a neutron and N is either a neutron or a proton) of the hypernucleus $_Λ^4$He. Using a three-body model the effects of distortion of the interaction of the emitted nucleon pair with the residual nucleus is considered. We also study the influence of the final state interaction between the emitted nucleons using the Migdal-Watson model. The effect of spin symmetries in the final state of the pair is also considered. Based on our calculations, we conclude that final state interactions play a minor role in the kinetic energy spectrum of the emitted nucleon pair.
