Notes. The full version of this table is available at Zenodo, including parameters corresponding to the interaction space of Table 1. (a)Parameter values determined in the ab initio pseudo-relativistic Hartree-Fock (HFR) and least-squares-fitted (LSF) calculations and their ratio. Standard deviations of the fitted LSF parameters are in parentheses, where ‘f’ means the parameter was fixed. (b)Parameters in each numbered group (G) were linked together by sharing the same ratios to their corresponding HFR values. (c)Differences between LSF and HFR parameters are given for Eav in this extract.
