Publikováno v: Journal of Radioanalytical and Nuclear Chemistry. 270:379-384

The correlations of isomer shifts in various neptunyl(V and VI) compounds with crystallographic structures were revaluated. A linear correlation between the isomer shifts of neptunyl(VI) compounds and Np-O bond lengths of neptunyl group has been demo
