利用折叠模型势，系统地分析了轰击能在65 <E p <200MeV之间的质子弹性散射。在核物质中的Brueckner Hartree-Fock近似下，对密度和入射能量相关的有效相互作用进行了微观评价。截面、分析幂和自旋函数的实验数据都能得到满意的再现。特别是在E p =65 MeV时的数据的拟合质量非常好。结果表明，介质效应在该能量区仍起着重要作用。研究了有效相互作用对折叠模型电位的影响。发现泡利和启动能量重排势使折叠势的净深度减少了15%以上。讨论了折叠过程中存在的一些问题。
Systematic analyses of proton elastic scattering from nuclei between the bombarding energies of 65 <E p <200MeV were performed with use of the folding model potentials. The density- and incident energy-dependent effective interactions to be folded were evaluated microscopically under the Brueckner Hartree-Fock approximation in nuclear matter. The experimental data of cross sections, analyzing powers and spin rotation functions could be reproduced satisfactorily. Especially the quality of fit was excellent for the data at E p =65 MeV. It was shown that the medium effects still play important roles in this energy region. Dependence of the folding model potential on the effective interactions was also investigated. The Pauli- and starting energy-rearrangement potentials were found to reduce the net depth of the folding potential by more than 15%. Some problems in the folding procedure were also discussed.
