Applicability of these criteria is illustrated and compared for several approximate wave functions for the 1sσ_g and 2pσ_u states of the {H^+}_{2} molecule.}, pages = {6301--6303}, title = {Zero potential energy criterion for approximate wave functions}, volume = {83}, year = {1985}, yomi = {コガ, トシカツ} }
