Description

Using the transient field technique, the magnetic moments of the second excited 2+ states in Zr92,94 have been measured for the first time. The large positive g factors, g(22+;92Zr)=+0.76(50) and g(22+;94Zr)=+0.88(27), which are in contrast to the known negative g factors of the 21+ states, are found to be a consequence of weak proton-neutron coupling combined with the Z=40 subshell closure. From their large M1 transition strengths to the 21+ states, in earlier works an assignment to the 22+...[Show more]
