Abstract:

An array of escape suppressed germanium detectors has been used to study gamma-ray spectroscopy with a ¹⁹Ne radioactive beam of almost 10⁹ pps. High quality singles and coincidence spectra were observed from fusion-evaporation reactions populating nuclei with $A \sim 50$ and coincidences with charged evaporation products were found to be effective in identifying the reaction channels. The large backgrounds from radioactivity in the target and elsewhere were subtracted using a procedure that relied on the timing of events relative to the pulsed beam. Implications for future work are discussed.
