摘要：

Using deformed bosons we construct a generalized deformed harmonic oscillator which satisfies the same commutation relations as a system of fermion pairs of zero angular momentum in a single-j shell. The pairing energy is also exactly reproduced by this mapping. The spectrum of the generalized deformed oscillator corresponds, up to first order perturbation theory, to a harmonic oscillator with an x4 perturbation. A generalized deformed oscillator giving the same spectrum as a general anharmonic oscillator is also constructed.
