摘要
用相对论Brueckner—Hartree—Fock(RBHF)方法从微观现实的二体相互作用势出发求解相对论Brueckner—Bethe—Goldstone(RBBG)方程导出相对论微观光学势。用这种相对论微观学位研究了入射能量范围从160到800MeV质子与^(16)O,^(40)Ca,^(90)Zr,^(208)Pb散射的微分截面和自旋观测量并与相对论唯象光学势计算进行了比较。并对RBHF方法,Walecka模型和相对论唯象光学位模型作了比较,同时分析了各种方法的优点及局限性。相对论核多体方法对有限核结构及天体物理研究也有着广泛的应用前景。
In the framework of a relativistic Brueckner-Hartree-Fock(RBHF) approach, the relativisitic microscopic optical potentials are derived from Relativistic Brueckner-Bethe-Goldstone (RBBG) equation using the real. istic nucleon-nucleon interaction. These relativistic microscopic optical potentials are used to study proton nucleus scattering with different targets; 16O, 40Ca,90Zr and 208Pb in the energy range from 160 to 800 MeV. The results, differential cross section and spin observables, calculated from RBBG at 200MeV are compared to those obtained in the relativistic phenomenological optical potential calculations. Advantages and limitations of various models, such as RBHF method, walecka model and relativistic phenomenological optical potential are discussed. The relativistic many-body method also provides useful tools of application in the nuclear sturcture of finite nuclei and astrnomy physics.
