Abstract

We present data for the reaction ${}^{40}{Ca} (p, 2 p) {}^{39}K$ at 148.2 MeV. Energy sharing cross sections for the ${\frac{3}{2}}^{+}$ ground state and $½^{+}$ excited state are well described by distorted-wave impulse-approximation calculations. An explicit comparison of the results of the factorization approximation with these experimental results provides considerable support for the usual distorted-wave impulse-approximation treatment.
