One commonly chosen solution to this problem (especially for heavy atoms such as Rb and Cs) is the attempt to summarize the effects of the core electrons in an effective averaged pseudopotential, which decreases the number of coefficients in the wave function (which still need to be optimized, of course). Note that pseudopotentials do not yield the true energy, and thus a direct comparison with energies based on AEBS calculations is not possible.

The starting basis set was a Stuttgart-Dresden ECP28MBW quasirelativistic pseudopotential with a core charge of nine and equal number of the valence electrons (Ref. 51). As no projection operators for l equal three are available in CRYSTAL 98 the terms for l = 3 were taken as local and were subtracted from the terms for l = 0, 1, and 2. An appropriate (7s6p) basis set contracted to [5s4p] was taken from the Stuttgart-Dresden pseudopotential homepage (Ref. 31). For numerical reasons, the most diffuse s functions and the most diffuse p function were omitted, and in order to allow the polarization of the 5s5p shell, a single d function (α = 0.3044) was added.
