The first muon spin rotation experiment / Garwin, Richard L
The February 15, 1957 issue of Physical Review Letters shows the first muon precession curve resulting from the stopping of `85 MeV' muons in graphite, and the resulting counting rate in a gate of fixed delay, duration, and orientation, as a function of an applied vertical magnetic field. The purpose of the four-day experiment was to test the conservation of parity in the weak interactions. [...]

$W^{+-}$-production in $e^{-}$ p-collisions at CERN LEP/LHC energies with a non-standard $W^{+-}$ anomalous magnetic moment / Gutiérrez-Rodríguez, A ; Rosado, A
We discuss the production of charged bosons in deep inelastic e-p- scattering, in the context of an electroweak model, in which the vector boson self interactions may be different from those prescribed by the electroweak standard model. We present results which show the strong dependence of the cross section on the anomalous magnetic dipole moment kappa of the W/sup +or-/. [...]

Positive muon diffusion in iron and nickel : pressure dependence / Butz, T ; Chappert, J ; Dufresne, J F ; Hartmann, O ; Karlsson, E ; Lindgren, B ; Longobardi, R ; Norlin, L O ; Pezzetti, J P ; Yaouanc, A
The hyperfine field B/sub hf/ at positive muon ( mu /sup +/) in iron and nickel was previously found. Exhibits marked deviations from the bulk magnetization as a function of temperature. [...]

Muonic Knight shift for simple metals in a linear-response model / De Renzi, R ; Dallacasa, V
The hyperfine contribution to the magnetic field at the mu /sup +/ site is calculated in the elementary dielectric-constant theory, which reveals itself to be suitable for simple metals, especially in the low-electron-density range. The model is compared with experimental data with better agreement than any previous theory, but still not in a completely satisfactory way. [...]

Muon diffusion in niobium in the presence of traps / Borghini, M ; Hartmann, O ; Karlsson, E ; Kehr, K W ; Niinikoski, T O ; Norlin, L O ; Pernestal, K ; Richter, D ; Soulié, J C ; Walker, E
Investigates muon diffusion in niobium with controlled amounts of interstitial impurities. The polarization decay was interpreted in terms of a two-state model where the muon is alternatively in a state of free diffusion or in traps. [...]

Some aspects of impurity trapping of muons / Karlsson, E
Several aspects of muon trapping in metals have been studied during the last two years, but the situation is still far from clear. The precise nature of the traps as well as the mechanisms leading to trapping seem to require more detailed investigations than those carried out so far. [...]

Muon diffusion in niobium in the presence of traps / Niinikoski, T O (CERN) ; Borghini, M (CERN) ; Hartmann, O (Inst. Phys., Uppsala) ; Karlsson, E (Inst. Phys., Uppsala) ; Kehr, K W (Jülich) ; Norlin, L O (Inst. Phys., Uppsala) ; Pernestål, K (Inst. Phys., Uppsala) ; Richter, D (Jülich) ; Soulié, L O (CERN) ; Walker, E (Geneva U.)
The first CERN experiments on Nb metal showed a behaviour of muon depolarisation rate Lambda (T) similar to that in Cu, but with indications of some structure in the 'flat' low-T region. Later measurements on more purified samples, containing less than 100 ppm substitutional impurities and varying concentrations of interstitial nitrogen, showed a very strong dependence of the depolarization rate on the nitrogen content.

Muon motion in pure and weakly doped aluminium / Niinikoski, T O ; Hartmann, O ; Karlsson, E ; Kehr, K W ; Norlin, L O ; Richter, D ; Welter, J M
The authors have studied the diffusion and localization of positive muons in pure and weakly doped aluminium, in the temperature range 30 mK-100K, by measuring the damping parameter of the muon spin rotation ( mu SR) signal. In this paper they discuss some of their recent results and draw the following conclusions: i) in pure Al, positive muons are delocalized in band states (coherent motion); ii) in Al doped with 5-70 ppm Mn, the temperature, concentration and field dependences of the damping parameter suggest diffusion or capture limited trapping to octahedral interstitial sites in the aluminium lattice below 1K; iii) above 2K a two-state diffusion-trapping model explains well the peak in the damping parameter, which appears at 15-50K for the dopants Mn, Mg, Li and Ag so far studied.
