Low-lying four-quasiparticle state in 82Rb

The g-factor of the 6⁺ 191.3 keV excited state with a half-life T_1/2=12.3(6) ns in ⁸²Rb populated in the ⁷⁹Br(⁴He,n) and ⁸¹Rb(³He,2n) reactions has been measured by the TDPAD method. On the basis of the experimental g-factor g_exp=+0.670(8) the four-quasiparticle configuration (left[ {pi g_{9/2} otimes nu left( {g_{9/2} } right)_{7/2}^3 } right]_{6^ + }) involving an anomalous neutron coupling has been assigned to this state.
