Abstract

Measurements of the ${}^{4}$He(${}^{7}\text{Be},\ensuremath{\alpha}$)${}^{7}$Be and ${}^{4}$He(${}^{7}\text{Be},p$)${}^{10}$B reactions were performed using ${}^{7}$Be beam energies of 7.1 and 23 MeV and a helium-4 target, employing the thick target technique. Resonances were observed between ${E}_{x}{(}^{11}\text{C})=8.6$ to 13.8 MeV. An $R$-matrix analysis was performed to characterize the spins and partial widths. This analysis showed that the observed sequence of states was consistent with that found for ${}^{7}$Li $+$ $\ensuremath{\alpha}$ resonant scattering populating resonances in ${}^{11}$B. A comparison of the proposed partial widths for decay with the Wigner limit indicates that several of the states are associated with cluster-like structures.
