论文摘要
在[J。 A.Rebouças和P. A.Brandão，物理。 Rev. A 104，063514（2021）]作者计算了$ \ Mathcal {p} \ Mathcal {t} $ - 对称的双尔达尔式功能在三个维度中的散射幅度，并通过调用Far-Zone近似近似值并汇总结果的出生系列。我们表明，对本文的分析遭受了基本错误。因此，其结果尚无定论。我们为该电位的散射幅度提供了精确的封闭式表达。
In [J. A. Rebouças and P. A. Brandão, Phys. Rev. A 104, 063514 (2021)] the authors compute the scattering amplitude for a $\mathcal{P}\mathcal{T}$-symmetric double-delta-function potential in three dimensions by invoking the far-zone approximation and summing the resulting Born series. We show that the analysis of this paper suffers from a basic error. Therefore its results are inconclusive. We give an exact closed-form expression for the scattering amplitude of this potential.
