Electric Field Gradients at Rubidium Sites in Rubidium Uranyl Nitrate and Quadrupole Moments in 85Rb and 87Rb
Abstract
The electronic structure along the axial direction of the uranyl ion in rubidium uranyl nitrate (RbUO2(NO3)3) has been studied by nuclear quadrupole resonance and nuclear magnetic resonance measurements of 85Rb and 87Rb quadrupole couplings. The parameter of interest in these experiments is the electric field gradient at the Rb sites, which may be compared with values com- puted by various theoretical approaches. From this analysis an accurate ratio of the quadrupole moments of 85Rb and 87Rb has also been obtained.Published: October 12, 2023
