Abstract
Hyperfine splittings in the 2, 2, and 2 states of the 45p configuration of (I=9/2) have been measured using saturated absorption laser spectroscopy. Computer simulations involving composite line shapes have been employed to reduce resolution difficulties. While the determination of hyperfine-coupling constants A and B in the 2 and 2 states is straightforward, this process is complicated by overdetermination in the 2 state. Our measurements of A (2) and (,2,2) represent the first determinations of these constants. With these measurements, hyperfine couplings for all eight states exhibiting hyperfine structure in the 45p manifold now exist. The results provide a good test of semiempirical calculations of hyperfine structures.
