球盒方法被扩展用于计算包含长程库仑相互作用的势中单粒子共振的共振参数和波函数的实部。采用模型势来证明该方法的能力和准确性。将计算出的共振参数与其他方法的可用结果进行比较。结果表明，在存在库仑相互作用的情况下，球盒方法对于不太广泛的共振效果很好。特别地，对于非常窄的谐振，本方法以非常高的精度给出谐振参数。
The spherical-box approach is extended to calculate the resonance parameters and the real part of the wavefunction for single particle resonances in a potential containing the long-range Coulomb interaction. A model potential is taken to demonstrate the ability and accuracy of this approach. The calculated resonance parameters are compared with available results from other methods. It is shown that in the presence of the Coulomb interaction, the spherical-box approach works well for not so broad resonances. In particular, for very narrow resonances, the present method gives resonance parameters to a very high precision.
