Electric Polarizability of Molecular Hydrogen as Calculated by Use of the Nonsymmetrical Wavefunction

摘要

The nonsymmetrical (NS) wavefunction has been employed to calculate the static electric dipole polarizability of the hydrogen molecule. It has been found that the double perturbation calculations carried through first order in electron correlation give results much better than those by zerothhyphen;order Hartreendash;Fock (HF) calculations and comparable to firsthyphen;order HF results with much less labor. Thus it appears better to obtain corrections to a starting wavefunction, even if it is exceedingly crude, rather than to find the best possible zerothhyphen;order approximation and stop there.
