Distorted-Wave Analysis of the Reaction $^{12}\mathrm{C}({$\pi${}}^{+}, {$\pi${}}^{+}p)^{11}\mathrm{B}$

A comparison of distorted-wave impulse-approximation calculations with recent ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}({\pi }^{+}, {\pi }^{+}p){}_{}{}^{11}{}_{}{}^{}\mathrm{B}$ data shows excellent agreement and demonstrates the applicability of the quasifree knockout reaction model. Both the shape and the magnitude of the energy-sharing distributions are well described by the calculations.
