• The g-factor of the 3190 keV 6^+ state in ^<42>Ca was measured by the time-differential perturbed-angular-distribution method in the ^<40>Ca(α,2p)^<42>Ca reaction. The result is g=-(0.50^<+0.02>_<-0.03>). Assuming the 0.99f^2_<7/2>+0.13f_<7/2>f_<5/2> configuration for the 6^+ state, the magnetic moment for the Of_<7/2> neutron is deduced to be -1.99_<μN>, being very different from the known magnetic moment of the ^<41>Ca ground state. The strong violation of the additivity relation is interpreted by a larger mixing of the core-excited deformed states into the ^<41>Ca ground state. The above magnetic moment for the Of_<7/2> neutron supports recent proposal that the orbital g-factor is enhanced in nuclei by around 0.1_<τz> if the quenching due to the second-order core polarization is taken into account.
