A detailed analysis found no evidence forO219300200004 the presence of 44Ti(a,p) reactions in the data, O219300200005 leading to an upper limit of 40 microbarn, at a 68% O219300200006 confidence limit. This is about half the NON-SMOKER O219300200007 prediction, and constitutes a step towards explaining O219300200008 the 44Ti excesses already observed in CCSNe. Future O219300200009 experimental studies utilising this and other isotopes O219300200010 reclaimed from accelerator waste are anticipated, O219300200011 with improved beam intensities expected.
