论文摘要
从相互作用电位的自旋依赖性的角度考虑弹性核子散射中的软衍射现象。分析了与弹性$ pp $散射，旋转依赖性差异截面和自旋相关参数分析的旋转依赖性波美龙效应。在扩展高能通用结构（HEGS）模型的框架中，根据$ \ sqrt {s} = 4.9 \ gev $从$ \ sqrt {s} = 4.9 \ gev $中检查自旋相关参数$ a_n $。结果表明，在衍射最小值和大动量转移处，质子 - 蛋白质和质子 - 抗抗原弹性散射的现有实验数据在高能区域中提供了支持，从而支持了强体自旋振幅的能量无关部分的存在。
Soft diffraction phenomena in elastic nucleon scattering are considered from the viewpoint of the spin dependence of the interaction potential. Spin-dependent pomeron effects are analyzed for elastic $pp$ scattering, spin-dependent differential cross sections and spin correlation parameters are calculated. The spin correlation parameter $A_N$ is examined on the basis of experimental data from $\sqrt{s} = 4.9 \ GeV$ up to $23.4 \ $GeV in the framework of the extended High Energy Generalized Structure (HEGS) model. It is shown that the existing experimental data of proton-proton and proton-antiproton elastic scattering at high energy in the region of the diffraction minimum and at large momentum transfer give the support of the existence of the energy-independent part of the hadron spin flip amplitude.
