✦ Synopsis

\n array of escape I-suppressed germanium detectors has been used to study gamma-Kily S]WCtlQSCOpJJ with a _ '"We radioactive beam of almost, 10" pps. High quality singles and coincitlencc~ sI)pctrn wpre observed from fusion-evaporation reactions populating nuc.lei wit,11 .-I N JO and coiucidences with charged evaporation products were found t,o bc c+f&ivc~ in ident,if\ring the reaction channels.

The large backgrounds from radioactivity in the t,argct and elsewhere were subtracted using a procedure that relied on the timing of (avent,s r&t,ive t,o t,ht? pulsed beam. Implications for fut,urc work are discussed.
