| Popis: | The polarization behavior of the phonon and electronic Raman intensities in PrVO{sub 4} and NdVO{sub 4} has been measured. These experimental intensities are compared with the intensities predicted by a polarization-dependent intensity theory. Good agreement was found between theory and experiment. The fitted values of the ratio F{sub 1}/F{sub 2} for PrVO{sub 4} and NdVO{sub 4} were found to be 1.0 and 0.48, respectively. The relative values of the {alpha}{sub q}{sup t} parameters obtained from the fit were compared with theoretical values which were derived using both second- and third-order theory, where the latter included the spin-orbit interaction. Axe{close_quote}s second-order theory was found to adequately explain the relative intensities of electronic Raman transitions in PrVO{sub 4} and NdVO{sub 4}. {copyright} {ital 1997} {ital The American Physical Society} |
