Abstract

We report magnetic dipole hyperfine-structure constants, obtained by doing nonrelativistic configuration-interaction calculations, for Ti47 i 3d24s2 3P, which are in excellent agreement with experiment [theory (experiment) A2=-23.150 (-25.215) MHz, A1=2.202 (2.665) MHz] in contrast with Hartree-Fock and some semiempirical values. Second-order electrostatic effects, arising mainly from the 3d34s configuration, are crucial to understanding this system. The nuclear quadrupole coupling constant is -138.4 MHz and 69.2 MHz×Q (in b) (J=1,2). By combining with measurement, we predict Q=0.346 b. Hyperfine-structure constants are also given for the 3d34s and 3d4 3P terms. © 1992 The American Physical Society.
