The ($p,2p$) reaction on the target nuclei $^{7}\mathrm{Li}$ and $^{12}\mathrm{C}$ has been studied at 100 MeV bombarding energy. The energies of both the outgoing protons have been measured in coincidence in a coplanar symmetric geometry with good energy and momentum resolution in order to separate the different excited states of the residual nuclei. The experimental data are presented in a form suitable for direct comparison with direct knockout theory (impulse approximation). The distorted wave impulse approximation model can explain the qualitative features of the energy sharing and angular correlation spectra. The detailed quantitative agreement with the distorted wave impulse approximation is, however, somewhat poor, indicating the necessity for a more exact treatment of the three-body reaction mechanism.NUCLEAR REACTIONS $^{7}\mathrm{Li}(p,2p)$, $^{12}\mathrm{C}(p,2p)$, ${E}_{p}=100$ MeV; measured $\ensuremath{\sigma}(E,{\ensuremath{\theta}}_{1},{\ensuremath{\theta}}_{2})$; deduced distorted recoil momentum distributions; separation energy resolution 0.8 MeV; DWIA analysis. |
