标题： Spin effects and relative momentum spectrum of two protons in deuteron charge-exchange breakup

摘要： 电荷交换破裂过程快中子d+p -> (pp)+n的微分截面与电荷转移过程n+p -> p+n的微分截面之间的关系在考虑质子身份效应以及最终态中质子的库仑和强相互作用影响的情况下进行了讨论。在冲量近似框架内找到了质子相对动量分布。结果表明，使用极化的初始中子和质子可以在零角度下分离电荷转移反应n+p -> p+n振幅中的两个自旋依赖项，并确定它们的相位差。研究了中子d波态的影响。 显示英文摘要

摘要： The relation between the differential cross section of the charge-exchange breakup of a fast deuteron d+p -> (pp)+n and the differential cross section of the charge transfer process n+p -> p+n is discussed taking into account the effects of the proton identity and of the Coulomb and strong interactions of protons in the final state. The distribution of the relative momenta of the protons is found in the framework of the impulse approach. It is shown that the use of polarized initial deuterons and protons allows one to separate two spin-dependent terms in the amplitude of the charge transfer reaction n+p -> p+n at zero angle and to determine their phase difference. The influence of the deuteron d-wave state is investigated.
