to lay outside well established nucleosynthesis processes. Boron is thought to have been formed
via Core Collapse Supernovae as well as via cosmic ray nucleosynthesis. Furthermore, there is
a possibility that vestiges of boron were produced during the Big Bang. It is an element whose
astrophysical origins facilitate a glimpse into some of the most extreme astrophysical processes
in the Universe. Boron’s stable isotopes, 10B and 11B, have therefore been studied for some
time. The single proton structure of the 11B isotope, however, is understudied. Understanding
this proton structure would provide useful insight, not only into nucleosynthesis, but into the
overarching knowledge of the isotope’s structure and neutron detection techniques as well. For
the purpose of studying this structure, the 10Be(p,n)10B reaction was measured at the Edwards
Accelerator Laboratory using the time of flight method, where a proton beam was incident on
a 90-μg/cm2 BeO target. A 0° excitation function was measured in the 2.0 ≤ Ep ≤ 7.0 MeV
energy range, and resonances were observed at Ep = 2.5, 3.5, and 5.7 MeV. Lastly, angular
distributions up to 150° were measured at 2.5 and 5.7 MeV.
