Abstract

Measurements of the hyperfine Zeeman transitions (ΔMμ=±1, ΔMJ=0) in the ground state of the muonic helium atom (He++4μ-e-) at magnetic fields of 11.5 and 13.6 kG have yielded values for the hfs interval, Δν=4465.004(29) MHz (6.5 ppm), and for the negative-muon magnetic moment, μμ-μp=3.183 28(15) (47 ppm). The theoretical value for Δν, including relativistic, radiative, and recoil contributions, agrees with our measured value but is much less precise because of inadequate knowledge of the Schrödinger wave function.
