Abstract
PAC measurements on the 4.43 MeV12C(2+) state on recoil in magnetized iron at velocitiesv ion=2.1v 0, 6.0v 0, 7.4v 0 yield integral precession angles of ϕ=+0.72(18), +0.94(16) and +0.71(18) mrad, respectively. The results supplementary to existing precession data are interpreted by a distribution of C5+ ions implying a K-shell polarization of ≃28% and an effective charge larger than measured after emergence from the solid. The low-velocity precession tends to disagree with the empirical law of linear relationship between transient field and ion velocity. The presence of molecular orbital effects is discussed.
