Calculation technique for quadrupole interactions in orthorhombic hydrides of ZrV2 Laves phase

Calculation technique for quadrupole parameters of complex lattices with two and more types of atoms by availability of multistage phase transitions in introduction structures is studied. The electrical field gradients tensor components, calculated according to the above technique, revealed the peculiarities characteristic of complex introduction phases on the ZrV2 intermetallic compound basis and made it possible to identify the NMR spectro in the area of the phase transition in the ZrV2-H system. The proposed scheme of sequential filling of internodes contains the evaluation of efficient hydrogen charge in tetragonal introduction phases.4 refs., 4 figs
