Mass formula in the restoration scheme of the Wigner SU(4) symmetry in heavy nuclei
Gaponov Yu. V., Shul'gina N. B., Vladimirov D. M.
The contribution of higher-order Casimir operators of the SU(4) group to the mass formula in the nuclei with A > 216 is investigated on the basis of the experimental data for nuclear-mass differences. It was found that the mass differences of isobaric nuclei are described in the restoration scheme of the SU(4)) symmetry with an accuracy of ~ 200 keV.
