Abstract
The dipole-dipole, dipole-quadrupole, dipole-octupole, quadrupole-quadrupole, dipole-dipole-dipole, dipole-dipole-quadrupole, dipole-quadrupole-quadrupole, quadrupole-quadrupole-quadrupole and dipole-dipole-octupole long range interaction coefficients for neon are calculated by time dependent Brueckner-Goldstone perturbation theory.
