Abstract :
A 4π Si-ball of about 5 cm diameter consisting of 12 pentagonal and 18 hexagonal silicon epitaxial n+-n-p+ detectors of sensitive thickness of 100 μm has been constructed. The energy resolution measured with 3.5 and 5.85 MeV α-particles from 148Gd and 241 Am sources, respectively, varied from about 30–90 keV for individual detectors. The main aim of constructing this device was to provide selection of reaction channels for in-beam spectroscopy. The first “in-beam” results for this Si-ball were obtained using the reaction 40Ca (200 MeV) + 58Ni→98Cd* in an experiment performed at GSI.
