Abstract Details

2013, Master of Science (MS), Ohio University, Physics and Astronomy (Arts and Sciences).
The neutron energy spectra of the 9Be(p,n)9B reaction have been studied at 4.50-, 2.107-, 2.002-, and 2.065-MeV proton energies via the neutron time-of-flight technique. The 4.5-MeV proton beam was incident on the 15-µm-thick 9Be target at the angles of 0°, 30°, 45°, 60°, 95°, 120°, and 149.8°. The differential cross section of the reaction at these angles was also determined. No evidence of the first excited state of the 9B nucleus was found in the range of 1-2 MeV excitation energy. This result could possibly be attributed to the fact that either this state is weakly populated or is very wide. The neutron energy spectra of the 9Be(p,n)9B reaction at proton energies near the threshold value were also studied. No narrow resonances were observed near the threshold of the 9Be(p,n)9B reaction which contradicts the previous observations.
