The Mössbauer effect has been studied in the 100-keV (2+→0+) transition in W182. Metallic tantalum was used as the source and metallic tungsten, powder of WO3 and single crystal of WO3 as the absorbers.
For the absorbers of powder of WO3 and single crystal quadrupole interaction was observed. The value of eQVzz (1−RA)=−3.5×10−6 eV was obtained. The electric field gradient at the nucleus of tungsten in the lattice of WO3 Was estimated to be 1.7×1018 Volt/cm2 and the asymmetric parameter η was proved to be approximately zero
