The measurement of electric quadrupole moments in nuclei far from stability provides a fundamental test for our understanding of nuclear structure. The experimental determination of this important quantity is based,
directly or indirectly, on measuring the interaction of the quadrupole moment of a nuclear excited state with an electric field gradient
(EFG). We discuss some of the challenges associated with the measurement of quadrupole moments using radioactive ion beams and specifically we present results on the use of the reorientation techniques in Coulomb
excitation to measure, for the first time, the quadrupole moment of the first 2+ of the radioactive nucleus 78Ge.
