Experiment used 20Ne + 12C --> 3n + 29S reaction, which was working nicely at MARA - no backscattering problems encountered. The beta-delayed proton decays from 29S were observed at the MARA focal plane shortly after the experiment started. This allowed the production rate to be investigated and optimized in terms of the beam energy: data was collected with the following beam energy [MeV]/target thickness [mg/cm2] combinations: 140/2 (~24 h), 125/2 (~24 h), 125/0.7 (~96 h), 145/0.7 (~24 h). At the end of the beam time, the beta-delayed proton tagged JUROGAM 3 spectrum showed at least 5 gamma-ray peaks originating from 29S and 3 of these were new transitions. This experiment used about 7 days of beam time but would have definitely benefitted from another week of beam time to improve the statistics.
