摘要：

We have measured the differential cross-sections and analyzing powers for (p, 2p) reactions at an incident energy of 392 MeV on C-12, O-16, Ca-40, and Pb-208 nuclei, leading to discrete states of the residual nuclei. The data are compared with two kinds of distorted-wave impulse approximation (DWIA) calculations, a standard calculation using a global optical potential and a calculation using wave functions generated in a relativistic Hartree model. The spectroscopic factors deduced from these two calculations agree with those determined in (e, e' p) studies mostly within 15% in the case of the lighter three target nuclei. However, those for the Pb-208 target are overestimated compared with the (e, e' p) results. In the heavy target case, the DWIA results are very sensitive to the radius parameter of the bound-state potential and thus a careful treatment is required. Regarding the analyzing powers of the present measurement, we confirmed that the j-dependence is sufficient for practical spectroscopic use.
