Web2 Nov 1985 · Superposition of atomic or ionic densities fails to give the correct charge density, because of the strong hybridization between the oxygen and nickel states in the real system. We expect atomic superposition to fail for a number of similar chemisorption systems, in which the charge density in the helium scattering region is dominated by … WebAbstractThe trial wave function $$\\varphi = \\left( {\\text{2}} \\right)^{ - 1/2} \\left( {a^2 + b^2 } \\right)^{1/2} $$ gives the classical electron density, ϱ. Contrary to the common belief, this electron density gives a very substantial covalent bonding for H2+and H2. The stabilization energy comes from a favorable kinetic energy. This in turn arises because …
