M.Sc. Juha Sorri defends his doctoral dissertation in Physics ”Electron spectroscopy with the SAGE spectrometer”. Opponent Professor Andreas Görgen (University of Oslo, Norja) and custos Professor  Paul Greenlees (University of Jyväskylä).

A device called the SAGE (Silicon And GErmanium) spectrometer, designed for in-beam electron spectroscopy, is introduced in this work. A detailed description to the technical aspects of the device is given along with several examples of analytical procedures related to work done with the device.

Two experiments with results obtained from the electron data are introduced and analysed. Coulomb excitation is used to probe 154Sm and a more typical fusion-evaporation reaction is used to produce 194Po. The 154Sm study is serves mainly for introduce the new analysis methods. In the 194Po analysis the mystery regarding the doublets in the electron spectrum measured earlier experiments is solved and a possible extension to the known level scheme of 194 Po is given.
