Abstract

From the time dependence of the (μ^-, nν) reaction we have determined the hyperfine transition rates for the muonic atoms of ¹⁹F, ²³Na, and ^natCl, obtaining Λ_h=4.9±1.2 μs^-1, 8.4±1.9 μs^-1, and 6.5±0.9 μs^-1, respectively. Further, from the branching ratios of the (μ^-1, ν) reaction on muonic ³¹P we have inferred a hyperfine transition rate that is much faster than the muon disappearance rate, Λ_h≫Λ_D. These results are in reasonable agreement with the rates calculated for Auger emission, and qualitatively confirm the correction to the muonic atom's hyperfine splitting due to the distribution of magnetism in the nucleus. The ³¹P result, however, disagrees with an earlier suggestion of the inhibition of Auger emission.
