论文摘要
我们采用非扰动时间依赖性基础函数（TBF）方法来解决deuteron弹丸在$^{208} $ PB目标上的亚库仑屏障散射。具体而言，我们将目标视为强大的外部库仑场的来源，该库仑场在迪特隆弹丸的电偶极激发中引起高阶效应，包括通过迪特伦基底的直接电动偶极转变无法获得的国家人群。我们计算杜特隆和弹性散射可观察物的电 - 偶极极化，以与实验数据进行比较。没有可调节的参数，TBF方法与实验可用的差异横截面比提供了良好的一致性。研究了这些测量量对核子核子相互作用的依赖性。我们还研究了详细的散射动力学，并确定相干和不相互分过程的特征。
We employ the non-perturbative time-dependent basis function (tBF) approach to solve for the sub-Coulomb barrier scattering of the deuteron projectile on the $^{208}$Pb target. Specifically, we treat the target as a source of a strong external Coulomb field that induces higher-order effects in electric-dipole excitations of the deuteron projectile including the population of states not accessible through direct electric-dipole transitions from the ground state of the deuteron. We calculate the electric-dipole polarizability of the deuteron and elastic scattering observables for comparison with experimental data. With no adjustable parameters, the tBF approach provides good agreement with experimentally available differential cross-section ratios. The dependence of these measured quantities on nucleon-nucleon interactions is investigated. We also investigate the detailed scattering dynamics and identify characteristics of coherent and incoherent processes.
