Abstract
The dynamical eikonal approximation unifies the semiclassical time-dependent and eikonal methods. It allows calculating differential cross sections for elastic scattering and breakup in a quantal way by taking into account interference effects. Good agreement is obtained with experiment for 11Be breakup on 208Pb. Dynamical effects are weak for elastic scattering.
摘要
动力学程函近似统一了含时半经典方法和程函方法。它通过考虑干涉效应，能够以量子力学的方式计算弹性散射和破裂的微分截面。对于(^{11}Be)与(^{208}Pb)的破裂反应，计算结果与实验结果吻合良好。而对于弹性散射，动力学效应较弱。
