    "abstract": "The role of center-of mass (CM) effects in the one-body nuclear current in\nthe description of electromagnetically induced two-nucleon knockout reactions\nis discussed in connection with the problem of the lack of orthogonality\nbetween initial bound states and final scattering states obtained by the use of\nan energy-dependent optical model potential. Results for the cross sections of\nthe exclusive $^{16}$O(e,e$\u0027$pp)$^{14}$C and $^{16}$O($\\gamma$,pp)$^{14}$C\nknockout reactions in different kinematics are presented and discussed. In\nsuper-parallel kinematics CM effects produce a strong enhancement of the\n$^{16}$O(e,e$\u0027$pp)$^{14}$C$_{\\rm g.s.}$ cross section which strongly reduces\nthe destructive interference between the one-body and $\\Delta$-current and the\nsensitivity to the treatment of the $\\Delta$-current found in previous work.",
