n+d散射模型中能区的Faddeev和Glauber计算

Faddeev and Glauber Calculations at Intermediate Energies in a Model for n+d Scattering

Ch. Elster, T. Lin, W. Gloeckle, S. Jeschonnek

摘要:

基于Glauber公式获得中能核反应截面有着悠久的传统。只是最近的能量制度的几百兆电子伏已成为访问的从头计算Faddeev三体散射。为了达到更高的能量,Faddeev方程的三体散射制定和直接解决,而不采用分波分解。相互作用标量粒子的Faddeev方程在最简单的形式下是一个五变量的三维积分方程,由此可以得到总截面、弹性散射和破碎反应的截面以及微分截面。相同的观测值是根据Glauber公式计算的。一阶Glauber计算和Glauber再散射修正进行了详细的比较,与相应的条款的Faddeev多次散射系列的弹丸能量在100 MeV和2 GeV之间。

英文摘要:

Obtaining cross sections for nuclear reactions at intermediate energies based on the Glauber formulation has a long tradition. Only recently the energy regime of a few hundred MeV has become accessible to ab-initio Faddeev calculations of three-body scattering. In order to go to higher energies, the Faddeev equation for three-body scattering is formulated and directly solved without employing a partial wave decomposition. In the simplest form the Faddeev equation for interacting scalar particles is a three-dimensional integral equation in five variables, from which the total cross section, the cross sections for elastic scattering and breakup reactions, as well as differential cross sections are obtained. The same observables are calculated based on the Glauber formulation. The first order Glauber calculation and the Glauber rescattering corrections are compared in detail with the corresponding terms of the Faddeev multiple scattering series for projectile energies between 100 MeV and 2 GeV.
