Abstract

With the time-differential angular distribution method the g-factor of the lowest 6^+-state in ^<42>Ca has been measured to be -0.52 ^^<+0.02>__<-0.03>, being closer to the Schmidt value for the 0f_<7/2> neutron than that of the ^<41>Ca ground state is. Strong violation of the additivity of the effective magnetic moment for these states is interpreted by a larger mixing of the core excited deformed states into the ^<41>Ca ground state.
