我们在Glauber模型中构造了考虑破裂效应的弱束缚射束弹性散射的微观光学势,其中核子-核子势是用矩阵折叠模型导出的。所导出的微观光学势称为Eikonal势。对于散射,用动能势即EP模型计算,合理地重现了中能区连续离散耦合道法的精确计算结果。从EP模型的性质中,部分排除了Glauber模型中使用的eikonal近似的不准确性。文中还分析了He对C的散射,并说明了它对多体弹丸散射的适用性。
We construct a microscopic optical potential including breakup effects for the elastic scattering of weakly binding projectiles within the Glauber model, in which a nucleon–nucleus potential is derived using the-matrix folding model. The derived microscopic optical potential is referred to as the eikonal potential. Forscattering, calculation with the eikonal potential, i.e., the EP model, reasonably reproduces the result of the exact calculation with the continuum-discretized coupled-channels method at intermediate energies. From the properties of the EP model, the inaccuracy of the eikonal approximation used in the Glauber model is partially excluded. Also analyzed with the eikonal potential is the scattering ofHe fromC, and its applicability to scattering with many-body projectiles is shown.
