摘要：

We present the first muon-spin-relaxation studies in superfluid He-4 in the temperature range 0.5-1.5 K. At temperatures below 1 K we observed muonium spin precession. From the magnetic-field dependence of the amplitude of the muonium component we estimate a muonium formation rate of about 5 x 10(7) s-1 at 0.5 K. We find that external electric fields, preventing the convergence of muon and electron, reduce the amplitude of the muonium precession signal.
