ATOMIC HYPERFINE STRUCTURE .2. FIRST-ORDER WAVE FUNCTIONS FOR GROUND STATES OF B,C,N,O, AND F

Ab initio computations of hyperfine structure have been made for the ground states of B, C, N, O, and F using a first-order wave function designed to include the strongly structure-dependent part of the electron distribution. The magnetic hyperfine constants are in poorer agreement with experiment than for the previously studied and less extensive polarization wave functions, but the discrepancies are more uniform, particularly for the spin density at the nucleus. © 1969 The American Physical Society.
