    "abstract": "We calculate the two-step contribution to (p,p\u0027) and (p,n) reactions at\nintermediate energy. We describe the motion of the incident nucleon with plane\nwave and compare the contribution from the two-step processes with that from\nthe one-step processes. To describe the two-step processes, we extende the\nresponse functions into the nondiagonal ones with respect to the momentum\ntransfer q.\n  We performed a numerical calculation for the cross sections of the $^{12}$C,\n$^{40}$Ca(p,p\u0027) scatterings and the spin longitudinal and the spin transverse\ncross sections of the $^{12}$C,$^{40}$Ca(p,n) reactions at 346 MeV and 494 MeV.\nWe found that the two-step contribution is appreciable in comparison with the\none-step processes in higher energy transfer region for the spin longitudinal\nand the spin transverse (p,n) reactions. We also found that the two-step\nprocesses give larger contribution to the spin transverse (p,n) reaction than\nto the spin longitudinal reaction. This finding is very encouraging to\ninterpret the discrepancy between the DWIA calculation and the experimental\nresults of the spin longitudinal and the spin transverse cross sections.",
