Abstract
Combined CI–HY method techniques have been employed in obtaining a 57‐term CI–HY wave function with an energy of −14.66632 a.u. A method due to Brown has been adopted for obtaining this wave function and various shorter expansions. A 44‐term expansion with an energy of −14.66606 a.u. is analyzed in terms of various pair effects, and qualitative arguments are presented for understanding these effects.

Configuration-interaction calculations are carried out for the ground and ionized states of the Be atom with various bases of numerical Xo orbitals. These bases prove to be moderately effective for correlating, the outer shell, while no correlation involving the inner electrons is achieved\_ This de
## Abstract Combined CI‐HY method calculations are reported for the ground and first three excited __S__ states of He with an error on the order of 10^−7^ a.u. within the same 120‐term basis. For He ^1^__P__, the four lowest states are obtained with an error ≤2 × 10^−6^ a.u. within the same 102‐ter
## Abstract Rate parameters for the reaction of ground‐state atomic sulfur, S(^3^__P__), with the olefins __cis__‐2‐butene and tetramethylethylene have been determined over a temperature range of ∽280°K. A major finding of this study was that the rate constants for both reactions showed negative te
