The adiabatic distorted wave approximation (ADWA) is widely used by the nuclear community to analyse deuteron stripping (d, p) experiments. It provides a quick way to take into account an important property of the reaction mechanism: deuteron breakup. In this work we provide a numerical quantification of a perturbative correction to this theory, recently proposed in Johnson (2014 J. Phys. G: Nucl. Part. Phys. 41 094005) for separable rank-one nucleon–proton potentials. The correction involves an additional, nonlocal, term in the effective deuteron–target ADWA potential in the entrance channel. We test the calculations with perturbative corrections against continuum-discretized coupled channel predictions which treat deuteron breakup exactly.

核界广泛使用绝热畸变波近似 (ADWA) 来分析氘核剥离 ( d , p ) 实验。它提供了一种快速的方法来考虑反应机制的一个重要特性：氘核分裂。在这项工作中，我们提供了对该理论的微扰校正的数值量化，该理论最近在 Johnson (2014 J. Phys. G: Nucl. Part. Phys. 41 094005) 中提出，用于可分离的一级核子 - 质子势。校正涉及入口通道中有效氘核靶 ADWA 电位中的一个额外的非局部项。我们使用微扰校正对连续离散耦合通道预测的计算进行了测试，这些预测准确地处理了氘核分裂。
