The level statistics of the spherical mean-field plus pairing model is investigated based on the exact solutions obtained from the extended Heine-Stieltjes correspondence. It is shown that the level statistics for 49Ca and 50Ca calculated from the model with single-particle energies and a pairing strength extracted from experimental data indeed exhibits a chaotic behavior within the phase transitional region, while most isotopes display regular spectra.
