论文摘要
我们介绍了Swanlop的包装，以计算散射波和相应的可观察到核子弹性碰撞的可观察结果。该代码能够处理局部和非局部光学电位，可超级与远程库仑相互作用。通过求解用于散射波段的Lippmann-Schinginger类型的积分方程，$ψ= ϕ__ {C} + {g} _ {c} _ {c} _ {c} {c} {u} {u} {u} _ {s} $，提供和确切的治疗效力[ Lett。 B 789，256（2019）]。已开发该软件包是为了在动量或坐标表示中处理潜力，并在每个方面提供了灵活的选项。该代码是完全独立的，尺寸为处理任何$ a \！\ geq \！4 $目标的核子束能量的目标，最高为1.1 GEV。提出和讨论准确性和基准应用。
We introduce the package SWANLOP to calculate scattering waves and corresponding observables for nucleon elastic collisions off spin-zero nuclei. The code is capable of handling local and nonlocal optical potentials superposed to long-range Coulomb interaction. Solutions to the implied Schrödinger integro-differential equation are obtained by solving an integral equation of Lippmann-Schwinger type for the scattering wavefunctions, $ψ=ϕ_{C} + {G}_{C} {U}_{S}ψ$, providing and exact treatment to the Coulomb force [Phys. Lett. B 789, 256 (2019)]. The package has been developed to handle potentials either in momentum or coordinate representations, providing flexible options under each of them. The code is fully self-contained, being dimensioned to handle any $A\!\geq\!4$ target for nucleon beam energies of up to 1.1 GeV. Accuracy and benchmark applications are presented and discussed.
