Abstract

In an attempt to explore a possible new technique for the measurement of quadrupole moments of short-lived states, we have searched for an internal quadrupole field induced by a possible transient electric field gradient acting on fast-moving ions in solids. In the measurement we attempted to detect perturbations of the angular correlation pattern of γ rays deexciting the first 2+ states in Fe56 and Mg24, which were both Coulomb excited in the interaction of 125-MeV Fe56 with Mg24. No electric field gradient effect was seen (≤1021 V/cm2). As a by-product, some information was obtained on vacuum deorientation coefficients for Fe56 and Mg24.
