Observation of +- F/sub 0/ symmetry in F-spin multiplets

Journal Article · · Mod. Phys. Letters B; (United States)
;
Pairs of conjugate nuclei with the same F-spin and +-F/sub 0/ values also have identical N/sub rho/N/sub n/ values. In the rare earth region, these +-F/sub 0/ pairs are symmetrically located with respect to the F/sub 0/ = 0, A = 164 isobar and their empirical excitation energy spectra are found to be very similar. An IBM-2 Hamiltonian with constant parameters has such a built-in symmetry and can explain the general trends except for the 2/sup +//sub ..gamma../ bandhead energies.
