FysiikkaA 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. The radial ltering
method and veto/add-back algorithms are tools for improving the quality
of the electron-gamma data whilst the time-gate selection procedure helps in
determining absolute internal conversion coe cients without reference points.
Two very di erent types of 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 and no
gains are made when compared to other recent works on this isotope. In the
194Po analysis, despite some experimental pitfalls, the mystery regarding the
doublets in the electron spectrum measured with SACRED is solved and a
possible extension to the known level scheme of 194Po is given.
