In order to perform conversion electron and γ - ray spectroscopy of odd-N fission isomers with small population cross sections, large solid angle coverage for the fission fragment detection is required. An economical solution is provided by the use of commercially available silicon solar cells. Two detector arrays were developed for conversion electron studies with Mini Oranges and γ - spectroscopic studies with the MINIBALL Spectrometer, respectively, aiming at the investigation of the fission isomers in 237Pu [1], following the 235U(α,2n) reaction.
