Microscopic formation of mixed-symmetry states
ORAL
Abstract
One-phonon fully symmetric (FS) and mixed-symmetry (MS) states have been found to have pure F-spin near the N=50 shell closure. In Zr isotopes the proton and neutron contributions forming FS and MS states are isopolarized. Hence, the $2^+_1$ states in $^{92,94}$Zr have negative g factors due to dominant neutron configurations. The isopolarization was experimentally proven measuring the g factors of the $2^+_2$ states in $^{92,94}$Zr to be large and positive. Final values will be presented, and brought into context of the formation of FS and MS states near shell closures.
