The authors have used the segmented focal plane detector of the Rochester Enge split-pole spectrograph to study the breakup of 87 MeV {sup 11}B ions incident on a {sup 12}C target into {sup 4}He and {sup 7}Li fragments at relative energies between 0 MeV and 4 MeV and at laboratory angles between 7.5{degrees} and 25{degrees}. The total kinetic energy spectra of the breakup fragments is dominated by elastic breakup (all reaction products are left in their ground state). The reconstructed relative energy spectra for elastic breakup are dominated by sequential breakup of {sup 11}B via the 9.27 MeV, 10.26 MeV, and 10.60 MeV excited states in {sup 11}B. The measured yields are compared with the calculated cross sections of exciting these states, using DWBA calculations and B(EL) values obtained from radiative capture measurements of {sup 4}He and {sup 7}Li.
