AbstractAbstract
[en] Negative muon lifetimes have been measured in 48 elements including four pairs of separated isotope targets (6Li, (6Li, 7Li, 10B, 11B, 12C, 13C, 16O, 18O). The experimental set-up and electronics logic were checked against the positive muon lifetime, which was measured to be 2197.0 ± 0.077 ns, in good agreement with the accepted value of 2197.120 ± 0.077 ns. Muons were produced by the backward decay of pions which were provided by the M20 beam channel at TRIUMF. The negative muon lifetimes were measured for all light elements except H and He. An improved accuracy has been achieved in Be, H, O,F, Ha, Cl, and K, and new measurements were peformed for 13C, 18O, Dy and Er. Strong isotope effects were observed in Li, B, and O, but there was no isotope effect in C. Our results in 6Li and 7Li were in good agreement with the predicted values by Lodder and Jonker. Our measurements confirm that the even-odd effect in heavy nuclei is not strong and the increase of the odd-Z capture rates is smaller than that expected from the quenching of the Cabitbo angle in large magnetic fields. The negative muon beam was also stopped in 23 metallic oxides in order to measure the atomic capture ratios. The number of muons captured by each element was deduced by lifetime analysis. Our result reproduced the periodic dependence and agreed well with earlier x-ray measurements. The results however are of higher accuracy and are liable to very different systematic errors, which gives added confidence to the overall situation

AbstractAbstract
[en] Electron binding energies in the wake of a swift negative ion such as a muon or an antiproton have been evaluated. The velocity distributions of electrons emerging from the solid at the ionic velocities are also estimated. These calculations could be of guidance to the experimental project of Yamazaki and co-workers directed to elucidate the nature of convoy electrons emerging from solids after the passage of swift ions

AbstractAbstract
[en] The spectral flux density n(T) of μ- emerging from a kapton moderator has been measured at low kinetic energies T using time-of-flight. From n(T) the stopping power S(T) of kapton was determined for 2.5 eV ≤ T ≤ 750 eV by means of the relation n(T)·S(T) = const. The measured n(T) was corrected for multiple scattering and T dependent incident spectrum. n(T)·S(T) behind a mylar wedge, a scintillator and a kapton foil coated with a copper sheet was calculated using the stopping power Sa obtained from proton atomic data starting from a Gaussian μ- distribution in momentum selected by a magnet spectrometer. At 750 eV S(T) is about ten times larger than the Sa values of the same μ- velocity, whereas at 2.5 eV S is nearly two orders of magnitude smaller than the corresponding extrapolated Sa

AbstractAbstract
[en] A combined analysis is carried out of the set of data on the relative probability of atomic capture of negatively charged mesons and the stopping cross sections of low-energy charged particles for elemental targets. It is shown that the oscillations of the probability of atomic capture of negative muons in various compounds can be explained on the basis of periodic oscillations of the atomic stopping power
