Abstract
A scattering chamber is described, which was constructed and installed at the KN3000 Van de Graaff accelerator in Florence, for a systematic study of proton and alpha elastic backscattering cross sections on li ght nuclei, as a function of both bombarding energy and scattering ang le. Sixteen silicon detectors, which can be cooled down to LN(2) tempe rature, have been mounted at backward angles from 95 degrees to 170 de grees. Test measurements show that an overall accuracy of the order of 1-2% is attainable for the cross section values. These measurements a lso point out that special care should be devoted to the determination of the effective target thickness under beam bombardment.
