EXPERIMENTAL-TECHNIQUES IN HEAVY-ION FUSION .1. GAMMA-RAY TECHNIQUES

The details of the gamma-ray technique for measuring heavy-ion fusion cross sections are described through the analysis of a particular expe riment involving the Si-28 + Si-28 system. All steps, going from the e xperimental procedure and the spectra identification to the evaluation of cross sections, are thoroughly discussed. The absolute normalizati on method used here is shown to give accurate results in spite of the unavoidable charge collection errors, which approximately cancel in th e method. Excitation functions for thirteen evaporation channels are p resented, five of which had not been published before.
