We have measured the wavelengths of the 4 f 7 2 -3 d 5 2 and the 4 f 5 2 -3 d 3 2 X-ray transitions in μ- 28 Si with the bent-crystal spectrometer at the SIN muon channel. The results are compared to the calculated transition wavelengths which inclu

Motivated by the importance of scalar particles in the current work on gauge theories of fundamental interactions, we have performed an improved muonic-atom experiment to search for long-range muon-hadron interactions. We remeasured the wavelengths o

With the crystal spectrometer at Muon Channel I at SIN we measured the 3d 5 2 -2p 3 2 X-ray transitions in muonic 25Mg and 27Al. The h.f.s. of the 2p 3 2 was resolved and the spectroscopic quadrupole moment of the nuclear ground states determined: Q(

Differential cross sections for elastic α-scattering from 40 Ca have been measured for 21 energies between 26 MeV and 47 MeV. Orthodox potential scattering using either a folding or a phenomenological potential is complete sufficient to explain the

A precision measurement with the SIN bent-crystal spectrometer of the wavelength of the $2{p}_{\frac{3}{2}}\ensuremath{-}1{s}_{\frac{1}{2}}$ transition in muonic $^{12}\mathrm{C}$ yields $\ensuremath{\lambda}=16.473766(89)$ pm, the accuracy being an

Elastic α-scattering on 40Ca, 50Ti and 52Cr was measured for many energies between 23 MeV and 80 MeV and angles between 20° and 174°. The data are interpreted with local optical potentials of generalized Woods-Saxon shape, and also with potentials

The magnetic hyperfine splitting (h.f.s.) in the 1s state of 7 Li has been measured with a precision of 1% using the bent-crystal spectrometer facility at the SIN muon channel. With an instrumental resolution of 2.5 eV FWHM the h.f.s. was completely

We have observed, with the bent-crystal spectrometer at SIN, the quadrupole splitting of the 2 p 3 2 state of muonic 27Al from a measurement of the 3 d 5 2 −2 p 3 2 X-ray transition. The spectroscopic quadrupole moment of 27Al is deduced: Q = +0.15

The wavelength of the 2 p 3 2 - ls 1 2 transition in muonic 12C was measured with a crystal spectrometer as 16.473765 (88) pm. With an improved model-independent analysis we deduce an rms charge radius for 12C of 2.4829 (19) fm. A 2.4 standard deviat
