Abstract
Monte-Carlo simulations for analysis of the9Be(3He, t)9B∗ reaction at 33 MeV using coincidences between the high-resolution Munich Q3D spectrograph and the large-acceptance Birmingham silicon detector array are presented. These focus on the identification of the proton break-up product and the application to evidencing the first excited1/2+ state. Identifying this state has posed a challenge for over 70 years, but would enable the mirror symmetry in this light system to be explored, giving insight into its possible clustered structure. Penetrabilities for the low excitation energy regime are calculated showing the efficacy of the proton-identification method.
Highlights
The unstable isotope, 9B has a half-life of approximately 6×10−19 s (Γ=0.54±0.21 keV [1]) and was first discovered in 1940 by Haxby and coworkers [2, 3]
