Structure of $^8$B through $^7$Be+p scattering
ORAL
Abstract
Cross sections for $^7$Be+p elastic and inelastic scattering were measured at the HRIBF. Beams of $^7$Be at 17 incident energies betweeen E$_{cm}$=0.5-3.4 MeV bombarded CH$_2$ targets. Scattered protons were detected in a silicon-strip detector array covering $\theta_{cm}$=70$^{\circ}$-150$^{\circ}$. We have performed a multi-level R-matrix analysis of the combined cross sections (about 400 data points) to determine properties of states in $^8$B. The inelastic scattering data provide evidence for positive-parity states that were previously unobserved but were predicted by theory. Results and implications will be discussed.
