“…4 With the assumed exponential time dependence of the perturbation in Ag the time constant 1/22Ag~--1/22g--~l/2=610(90) ns was evaluated. This result strongly favours quadrupole interactions as the dominating source of perturbation which was also found in earlier measurements [15,16].…”

A new experimental method for unveiling the strong hyperfine interactions of multielectron ion configurations is described. It consists in observing atomic spin precessions of nuclear-excited ions recoiling through vacuum in weak external transverse magnetic fields. Due to the strong hyperfine coupling the nuclear orientation follows the atomic precession, resulting in a rotation of the angular correlation of decay v-rays. The method is illustrated using the long-lived 197keV t9F (5/2 +) state as probe. The observed large precessions as well as the strong attenuations of the 7-angular correlations are well accounted for by considering all possible configurations resulting from the coupling of L-shell electrons in the relevant ionic charge states.
