Abstract
With the knowng-factor of the Coulomb excited first 2+-state in32S the transient magnetic field was determined for sulphur ions traversing Gd at a mean velocity of 16ν 0 (ν 0=c/137). The degree of polarization deduced for the dominating H-like ions, ¯p1s =0.10(3), agrees very well with that obtained at lower velocities. In addition, an upper limit of a transient electric field gradient was deduced from the particle-γ-angular correlation which is expected on theoretical grounds.
