ELECTRIC DIPOLE POLARIZABILITIES AND DIPOLE SHIELDING FACTORS OF NEON MAGNESIUM AND ARGON ATOMS FROM HARTREE-FOCK WAVE FUNCTIONS

Simultaneous integro-differential equations which are derived by the coupled Hartree-Fock approximation are solved self-consistently. By use of the solutions, the dipole polarizabilities and the shielding factors of Ne, Mg and Ar atoms are calculated. The obtained values of the polarizability of these atoms are 0.3494 Å3, 12.04 Å3and 1.570 Å3respectively (experimental values are 0.395 Å3, 7.0±1.8~7.4±1.8 Å3and 1.642 Å3respectively). The dipole shielding factors of these atoms are 0.9994, 1.002 and 1.014 respectively, and agree with the exact theoretical value 1.0 within 1%. © 1969, THE PHYSICAL SOCIETY OF JAPAN.
