Abstract

Elastic scattering of protons on $^{40} Ca$ , $^{58} Ni$ , $^{120} Sn$ , and $^{208} Pb$ nuclei is analyzed in the framework of the Born approximation and an optical model for energies of 150 to 320 MeV. Analytical expressions for the scattering amplitudes, differential cross sections and polarization observables are obtained both in the Born approximation and within an optical model approach. The differences between outcomes of these approaches are discussed.

Born近似与原子核弹性中能质子散射的光学模型

质子在40 Ca $^{40}{\rm Ca}$, 58 Ni $^{58}{\rm Ni}$上的弹性散射在玻恩近似和能量为150 ~ 320 MeV的光学模型的框架下，对120个Sn $^{120}{\rm Sn}$和208个Pb $^{208}{\rm Pb}$原子核进行了分析。在玻恩近似和光学模型方法中得到了散射振幅、微分截面和偏振观测值的解析表达式。讨论了这些方法的结果之间的差异。

期刊介绍： Annalen der Physik (AdP) is one of the world''s most renowned physics journals with an over 225 years'' tradition of excellence. Based on the fame of seminal papers by Einstein, Planck and many others, the journal is now tuned towards today''s most exciting findings including the annual Nobel Lectures. AdP comprises all areas of physics, with particular emphasis on important, significant and highly relevant results. Topics range from fundamental research to forefront applications including dynamic and interdisciplinary fields. The journal covers theory, simulation and experiment, e.g., but not exclusively, in condensed matter, quantum physics, photonics, materials physics, high energy, gravitation and astrophysics. It welcomes Rapid Research Letters, Original Papers, Review and Feature Articles.
