✦ Synopsis

htuonium 113s been observed in ncopcntanc and tctramctbylsd~nc by a pulsed hluSR method. Tbc prohJb&ty ofmuomum formatIon was = 2W, and its rclaxtion times wcrc 8 and 2 6 US for bquid ncopcntanc and tctramclbylsdrnc, rcsPechvcly The rate of muomum rclz~hon has been shown to bc corrclolcd acll wtb rhc dasocmtlon cncrgy of IIIC C-H bond-1°C niques based upon the large difference m the magnetic moment between p+ and Mu [I 1. htuonium has been observed in water [2,3], alcohols [4], and saturated hydrocarbons 151. In all of these liquids, ~20% of the muons form hlu, and the relaxation time IS also measured to be between 0.5 and 20 p. The mecharusms of Mu formation and its relaxation are not well understood. The Mu relaxation time in H,O measured both at SIN [2] and TRIUMF [3] was coincidentally =4 us, but a recent
