Hyperfine Structure and Nuclear Magnetic Moment of K42
Abstract
The hyperfine structure in the 2S12 electronic ground state of K42 (12.4-h) has been studied using a high-precision atomic-beam apparatus. The hyperfine separation is shown to be Δν=1 258 876 947 (15) Hz. The nuclear magnetic dipole moment, measured independently of Δν, is μI=1.142 4(2) μN. The hyperfine magnetic anomaly is evaluated as 39Δ42=+0.000 3+0.003 36(38).
