Abstract
A PAC measurement on the 4.43 MeV12C(2+) state on recoil in magnetized iron has yielded an integral precession angle of ϕ=+0.85(14) mrad, which exceeds the Lindhard-Winther prediction by about two orders of magnitude. Evidently, large magnetic fields act at nuclei traversing solids at high velocities (v rec/c = 0.03 in the present case), thereby holding out the prospect ofg-factor measurements for nuclear states in this lifetime range (τ 2 + = 6.5 × 10−14 s).
