Table 4: Experimental and computed spectral moments of the isotropic CILS spectrum of Xenon. Experimental moments are extrapolated from the experimental intensities published by PKF [2] and CR [5]. Three potentials (BFW, MTT, UP [8]) and three anisotropy models (PM, B3LYP [6], MP2 [6]) are considered
