Long range dispersion interactions of the low lying states of Mg with H, He, Ne, Ar, Kr and Xe

The dispersion coefficients for the van der Waals interactions for the low lying states of magnesium (3s 1Se, 3s3p 3Po, 3s3pPo, 3s4s 3Se, 3s4s 1Se, 3s3d 3De and 3s3d 1De) interacting with H, He, Ne, Ar, Kr and Xe are determined using sum rules of reduced matrix elements over pseudo-state representations of the atomic excitation spectra. The sets of transition matrix elements were taken from previous investigations of the van der Waals interactions of the Mg2 dimer and an investigation of the van der Waals interaction for alkali atoms interacting with rare gases.
