B9excited states and analysis of theBe9(3He,t) spectra

Inclusive spectra of ${(}^3$He,t) on ${}_{}{}^9{}_{}{}^{}\mathrm{Be}$ have been measured and analyzed in a large energy range of emitted tritons at $E_{{\mathrm{}}^3\mathrm{He}=90\mathrm{}}$ MeV in the angular range 7°–27°. The spectra have been analyzed in terms of a superposition of simultaneous breakups, quasifree reactions, and two-step-fragmentation plus pickup processes. The residual spectra correspond to excited states in ${}_{}{}^9{}_{}{}^{}\mathrm{B}$. Confirmation for uncertain states was obtained. Some new states, possible analogs to ${}_{}{}^9{}_{}{}^{}\mathrm{Be}$, were observed.
