Title: Large multiconfiguration Hartree--Fock calculations on the hyperfine structure of B( sup 2 P ) and the nuclear quadrupole moments of sup 10 B and sup 11 B

Abstract

The hyperfine parameters for B({sup 2}{ital P}) are studied using numerical multiconfiguration Hartree--Fock (MCHF) calculations. A newly developed finite-element MCHF program allowing very large configuration--interaction expansions is used. The magnetic hyperfine parameters obtained are 0.0879(28), 0.7817(11), and {minus}0.1675(3) a.u. for the Fermi contact term, the orbital term, and the spin--dipolar term, respectively, as compared to the experimental values of 0.1016(62), 0.7783(16), and {minus}0.1686(5) a.u. The nuclear quadrupole moments obtained by comparing computed electric field gradients with experimental nuclear quadrupole couplings constants are {ital Q}({sup 10}B)=0.084 59(24) {ital b} and {ital Q}({sup 11}B)=0.040 59(10) {ital b}.
