摘要

摘要在俄罗斯莫斯科俄罗斯科学院核研究所的 RADEX 中子通道中，提出了一项实验，以确定中子能量为 5 MeV 时 nd 分裂反应中 np 相互作用的低能参数。虚拟 1S0 状态的能量和 np 散射长度可以从反应产率对破裂中子和质子在运动区的相对运动能量的实验依赖性中获得，在该运动区，最终状态中的 np 相互作用最为明显。对反应事件进行了模拟，并在此基础上选择了未来实验的最佳条件。

Simulation and Selection of the Optimal Experimental Conditions to Determine the Low-Energy Parameters of the np Interaction in the nd Breakup Reaction at a Neutron Energy of 5 MeV

An experiment was proposed to determine the low-energy parameters of the np interaction in the nd breakup reaction at a neutron energy of 5 MeV in the RADEX neutron channel, Institute for Nuclear Research, Russian Academy of Sciences, Moscow, Russia. The energy of the virtual ¹S₀ state and the np scattering length can be obtained from the experimental dependence of the reaction yield on the relative energy of motion of the breakup neutron and proton in the kinematic region, where the np interaction in the final state is most pronounced. The reaction events were simulated, based on which the optimal conditions for the future experiment were selected.
