摘　　要：We have performed two kinds of non-linear fitting procedures to the single-particle energies in the sdgh major shell to obtain better shell model results. The low-lying energy eigenvaiues of the light Sn isotopes with A = 103 - 110 in the sdgh-shell are calculated in the framework of the nuclear shell model by using CD-Bonn two-body effective nucleon- nucleon interaction. The obtained energy eigenvalues are fitted to the corresponding experimental values by using two different non-linear fitting procedures, i.e., downhill simplex method and clonai selection method. The unknown single-particle energies of the states 2s1/2, ld3/2, and Oh11/2 are used in the fitting methods to obtain better spectra of the 104,106,108,110Sn isotopes, We compare the energy spectra of the 104,106,108,110Sn and 103,105,107,109Sn isotopes with/without a nonlinear fit to the experimental results.
