CORE-VALENCE SEPARATION IN THE STUDY OF ATOMIC CLUSTERS 163
since

From (24) and (25) it follows that all the matrix elements can be obtained by
calculation over the set of "valence" functions, with the addition of terms relating to
single atoms.
Numerical applications to particular clusters are wery encouraging [7-11].
