It results from Hund's rules and means that the two d electrons form the highly- correlated electron system with the importance of the intra-atomic spin-orbit coupling. Keywords: highly-correlated electron system, crystal-field, spin- orbit coupling, orbital moment, V3+ ion. PACS: 71.70.E, 75.10.D, 75.30.Gw2 pages in RevTex, no figureStrongly Correlated Electronstext
