The O081000100015 18-O/2 gas was of high purity, >99.9% in chemical O081000100016 composition and 96.6% in isotopic enrichment, and an O081000100017 aluminum disk of high purity (99.999%) has been used asO081000100018 the sputtering cathode.

The combination of the high resolution O081000100026 Ge detector and the high-efficiency BGO scintillators O081000100027 was instrumental for achieving the required detection O081000100028 sensitivity for investigating the very weak resonances O081000100029 at astrophysical energies. The remarkable stability ofO081000100030 the sputtered targets under the thermal load of high O081000100031 beam currents is an additional parameter contributing O081000100032 to the success of the measurement.
