A part-per-million measurement of the positive muon lifetime and a determination of the Fermi constant
The mean life of the positive muon has been measured to part-per-million precision using a time-structured beam, a ferromagnetic target, and a fast, multi-segmented and symmetric scintillator detection array. The result, based on data acquired in 2006, is $\tau_{\mu^+} = \unit[2196980.1 \pm 2.6 \pm …

Muon-Catalyzed Fusion Effects in the Precision Measurement of Muon Capture on the Deuteron
The MuSun experiment will measure the rate of muon capture on the deuteron to 1.5~\% precision. This reaction is related to solar $pp$ fusion and the $\nu d$ scattering reaction at the Sudbury Neutrino Observatory through effective field theories like chiral perturbation theory. The Gamow-Teller …

Neutron Emission Following Nuclear Muon Capture in Al
… this study, and includes a measurement of the muon lifetime when captured by Al, Ti, and Pb with results of 864 ± 2, 341 ± 1, and 78 ± 1 ns, respectively. Neutron recoils are measured using two BC501a detectors by removing gamma interactions using an integrated charge comparison method for …

A measurement of the mean life of the positive muon to a precision of 11 parts per million
The mean life of the positive muon has been measured to a precision of 11 ppm using a low-energy, pulsed muon beam stopped in a ferromagnetic target, which was surrounded by a scintillator detector array. The result, τμ = 2.197 013 (24) μs, is in excellent agreement with the previous world average. …
