摘要：
Based on Schrodinger equation, the method of analytical continuation in the coupling constant (ACCC) is employed to investigate the energy and width of single-particle resonance in spherically symmetric square well, harmonic oscillator potential and Woods-Saxon potential. The influences of the interval for the coupling constant values and the order of Pade polynomial are analyzed. It has been shown that, by properly chosen interval for the coupling constant values and the order of Pade polynomial, stable and convergent energy and width of single-particle resonance can be obtained.
