中子-质子系统的相对论多级相互作用核
Relativistic multirank interaction kernels of the neutron-proton system
摘要：
本文提出了非耦合$S$和$P$分波（总角动量$J$ = 0，1）的中子-质子相互作用的多秩可分核.两种不同的方法被认为是一个相对论性的推广最初非相对论性形状因子参数化的内核。使用所构造的核的实验数据中的弹性中子-质子散射的相移的实验室能量高达3 GeV和低能量参数进行了说明。我们的结果与其他模型计算的比较。
英文摘要：
The multirank separable kernels of the neutron-proton interaction for uncoupled $S$ and $P$ partial waves (with the total angular momentum $J$=0,1) are proposed. Two different methods of a relativistic generalization of initially nonrelativistic form factors parametrizing the kernel are considered. Using the constructed kernels the experimental data for phase shifts in the elastic neutron-proton scattering for the laboratory energy up to 3 GeV and low-energy parameters are described. The comparison of our results with other model calculations are presented.
