Description
We have used the spin-precession technique to measure the Σ- magnetic moment (μ/sub Σ/). A Σ- beam with a polarization of 22% was produced by a 400-GeV proton beam striking a Cu target at nominal production angles of +- 3 mrad. We simultaneously recorded 21X0 Σ-→ne-nu-bar decays and 650X0 Σ-→nπ- decays at Σ- beam momenta of 253 and 308 GeV/c. We find that μ/sub Σ/ = -1.166 +- 0.014 +- 0.010 nuclear magnetons, where the quoted errors are statistical and systematic, respectively
