色散光学模型应用于转移反应。利用有限范围绝热反应模型，系统地研究了几种束流能量下闭壳核上的$(d,p)$反应，并将结果与数据以及使用标准全局光势的预测结果进行了比较。总的来说，我们发现色散光学模型能够更好地描述角度分布，甚至优于全局参数化。此外，它还约束了重叠函数。使用色散光学模型提取的光谱因子通常低于使用标准参数提取的光谱因子，对光束能量的依赖性降低，并且更符合从$(e,e'p)$测量得到的结果。
The dispersive optical-model is applied to transfer reactions. A systematic study of $(d,p)$ reactions on closed-shell nuclei using the finite-range adiabatic reaction model is performed at several beam energies and results are compared to data as well as to predictions using a standard global optical-potential. Overall, we find that the dispersive optical-model is able to describe the angular distributions as well as or better than the global parameterization. In addition, it also constrains the overlap function. Spectroscopic factors extracted using the dispersive optical-model are generally lower than those using standard parameters, exhibit a reduced dependence on beam energy, and are more in line with results obtained from $(e,e'p)$ measurements.
