Breakup of 87 MeVB11

A segmented focal plane detector has been used to study the breakup of 87 MeV $^{11}\mathrm{B}$ ions incident on a $^{12}\mathrm{C}$ target into $^{4}\mathrm{He}$ and $^{7}\mathrm{Li}$ fragments at relative energies between 0 and 4 MeV. The relative energy spectra are dominated by sequential breakup of the 9.28 MeV, 10.26+10.33 MeV, and 10.60 MeV excited states in $^{11}\mathrm{B}$. The measured breakup yields decrease with increasing center-of-mass scattering angle, consistent with predictions made using single-step inelastic distorted wave Born approximation calculations. Applications of this technique to study the breakup of $^{16}\mathrm{O}$ at low relative energies will be discussed.
