标题： Scattering of a relativistic scalar particle by a cusp potential

摘要： 我们在存在空间一维尖点势的情况下求解克莱因-戈登方程。 散射解用惠特aker函数表示，推导出透射共振存在的条件。 我们展示了零反射条件与势形状的依赖关系。 在低动量极限下，透射共振与半束缚态相关。 我们将透射共振的条件用相移来表示。 显示英文摘要

摘要： We solve the Klein-Gordon equation in the presence of a spatially one-dimensional cusp potential. The scattering solutions are obtained in terms of Whittaker functions and the condition for the existence of transmission resonances is derived. We show the dependence of the zero-reflection condition on the shape of the potential. In the low momentum limit, transmission resonances are associated with half-bound states. We express the condition for transmission resonances in terms of the phase shifts.
