CONTRACTED GAUSSIAN-TYPE BASIS FUNCTIONS REVISITED .2. ATOMS NA THROUGH AR

We report five minimal-type contracted Gaussian-type function (CGTF) b asis sets of the second-row atoms, Na - Ar, for molecular applications . Three of the present CGTF sets are revised versions of those given b y Huzinaga and co-workers and the other two are newly developed for mo re accurate calculations. Practical utility and improved reliability o f the present basis sets, augmented by polarization functions, are con firmed by test calculations on the P atom and P-2 molecule both at the self-consistent field (SCF) and configuration interaction (CI) levels .
