Mixed perovskites Ca1−x Srx HfO3 with x¡­=1−x Srx HfO3 with x¡­= 0.25, 0.50 and 0.75 have been prepared  for the first time by the high temperature solid state reaction method. The crystalline structures of these perovskites were investigated by X-Ray Diffraction (XRD) technique. The samples were irradiated with thermal neutrons to produce the 181Hf-181Ta Perturbed Angular Correlation spectroscopy (PACs) probe. A static asymmetric and disordered electric field gradient interaction was used to fit the time spectra. The behaviour of the Angular Correlation spectroscopy (PACs) probe.
