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 rays deexciting the first states in and , which were both Coulomb excited in the interaction of 125-MeV with . No electric field gradient effect was seen (≤ V/). As a by-product, some information was obtained on vacuum deorientation coefficients for and .
