| Abstract: | PAC measurements on the 4.43 MeV 12C(2+) state on recoil in magnetized iron at velocities υion = 0.058c, 0.071c yield integral nuclear precession angles of Φ = ?0.18 (30), +0.17 (39) mrad respectively. Evidently, the high electron-spin-polarization transfer to the innermost carbon orbits implied by a previous measurement (υion = 0.03c, Φ = +0.85 (14) mrad) is suppressed at higher ion velocities. |
