We studied the nuclear quadrupole interaction (NQI) at133Ba(EC)133Cs in Eu1Ba2Cu3O7–6 by time differential perturbed angular correlation between 11 K and 300 K. No anomalies in the NQI parameters around Tc were detected. All Ba sites appear to be identical and the precession frequency is ω=80(2) Mrad/s (assuming axial symmetry), independent of temperature.
