摘要：

Second order supersymmetry transformations which involve a pair of complex conjugate factorization energies and lead to real nonsingular potentials are analyzed. The generation of complex potentials with real spectra is also studied. The theory is applied to the free particle, one-soliton well and one-dimensional harmonic oscillator.
