论文摘要
考虑了质子在靶核的核子上的多个狄拉克菌散射的改进模型。在该模型中，通过dirac繁殖器的二元散射，在核子上的散射事件之间进行自由质子运动，并且在相对论的平均均值现场模型中描述了弹性$ p-a $散射的幅度。对于弹性$ p+^{40} $ ca和$ p+^{208} $ pb散射的弹性$ p+^{40} $ ca的完整可观察到的计算。已经研究了允许区分相对论标量和矢量核子密度对$ p-a $散射可观察物的描述的影响，并比较了使用相对论均值场模型的不同现代变体获得的核子密度的计算结果。
An improved model of the multiple Dirac eikonal scattering of proton on nucleons of the target nucleus is considered. In this model, the amplitudes of elastic $p-A$ scattering are found on the basis of the Watson series of multiple scattering by means of the eikonal expansion of the Dirac propagator for the free proton motion between scattering events on nucleons, and the nucleus structure is described in the relativistic mean field model. The calculations have been performed for the complete set of observables for the elastic $p+^{40}$Ca and $p+^{208}$Pb scattering at 800 MeV. The effects of allowing for distinction between the relativistic scalar and vector nucleon densities on the description of the $p-A$ scattering observables have been studied, as well as the results of calculations using nucleon densities obtained in different modern variants of the relativistic mean field model have been compared.
