Abstract
Perturbed angular-correlation techniques are proposed for measuring the spin precessions of a polarized nucleus interacting with an axially symmetric electric field gradient. A specific method is suggested which makes use of Coulomb excitation to polarize and excite a nuclear state even as it recoils the nucleus into a suitable crystalline environment. Calculations indicate that this spectroscopic technique should make practical the measurements of the sign and magnitude of quadrupole moments of subnanosecond nuclear states.
