- The MEGA experiment, which searched for the muon- and electron-number violating decay μ +→e + γ, is described. The spectrometer system, the calibrations, the data taking procedures, the data analysis, and the sensitivity of the experiment are discussed. The most stringent upper limit on the branching ratio, B(μ + →e + γ)<1.2×10 -11 with 90% confidence, is derived from a likelihood analysis.

- High-spin states in Gd-142 have been populated by means of the Ru-99(Ti-48, 2p3n) reaction at 2-10 MeV and investigated with the gamma-spectrometer EUROBALL III and the charged-particle detector array ISIS. The features of four dipole bands have been determined and compared with tilted-axis cranking model calculations indicating that they are magnetic rotational bands. A transition from regular to irregular bands has been found approaching N = 82 demonstrating that this is a general phenomenon in nuclei near a double-shell closure.

- The magnetic and ordering properties of (Fe1-xCox)(3)P (x=0, 0.1, 0.2, and 0.33) compounds have been studied by Fe-57 Mossbauer technique. These investigations show that Co preferentially substitutes Fe in two out of three metal sites. Variations of the m

Tidskriftsartikel (refereegranskat)abstract
- Synthetic compounds with the bulk composition Fe9+xCu9-xS16, x = 0, 0.2, 0.4, 0.6 and 0.8, were studied with Mossbauer spectroscopy and powder XRD. The hyperfine parameters were determined in the temperature range 6-295 K. A model for local environments o
