## 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

## Abstract New techniques have been developed for atomic self‐consistent‐field calculations by numerical integration. For the origin and tail regions we present analytical expansions which can represent the solutions to high accuracy. For the numerical integration in the central region a five‐poin
