After traversing a Flight Path D=27 Cm in a O047800100015 time 'T' Reaction Products were stopped in a Silicon O047800100016 Surface Barrier Detector which yielded a timing pulse O047800100017 as well as signal proportional to the Particle Energy O047800100018 'E'. The relationship 'E*T**2=M*D**2/2' then identifiedO047800100019 the Mass 'M' of the Particles.

O047800200006 ANALYSIS (INTED) O047800200007 COMMENT /by Authors/.Since Be-10 has a Life-Time of about O047800200008 1.0E+6 Years and hence does not necessarily decay to O047800200009 B-10 on Astrophysical Time Scale, it is in principle O047800200010 necessary to distinguish it from the other Mass-10 O047800200011 Isobars. O047800200012 Thus the Present Measurements at 30.0 and 33.7 MeV are O047800200013 entirely unaffected and Be-10 contributes perhaps 4% ofO047800200014 the Mass-10 Yield at the Higher Energies.
