✦ Synopsis
The static eIectricquadnrpole ïnteraction at the central merel síte has been determined in the series of alkali metal tetrakisoxaIatohafniates M4Rf(CsO4)4*nHsO usìng timedïfferentïal perturbed angular correlations of the rslTa 133-482 keV 7-7 cascade. The ïnfluence of the geoznetrïcal dbtortions of the Hf08 dodecahedron on the electxic field gradient is discussed. The results obtaïned for the sodïum and the potassium salts can be coherently interpreted with the point charge model ïf the true ConfgUration of the Hf08 groups is used.
