Etude des interactions quadrupolaires dans quelques tungstates par resonance Mössbauer de 182W

The tungstates having a double-perovskite, trirutile, scheelite or a wolframite type structure have been studied by means of Mössbauer 182W spectroscopy. It is shown that the electric field gradient at the W nucleus is essentially due to a lattice term in the scheelite structure while the valence te...

Description
Summary:The tungstates having a double-perovskite, trirutile, scheelite or a wolframite type structure have been studied by means of Mössbauer 182W spectroscopy. It is shown that the electric field gradient at the W nucleus is essentially due to a lattice term in the scheelite structure while the valence term seems to be preponderant in the case of the wolframite structure.
