    "abstract": "Dilepton production following radiative capture of a proton on a nuclear\ntarget is studied in the Impulse Approximation. The cross section is decomposed\nin terms of four time-like nuclear structure functions through a\nlongitudinal-transverse separation of the nuclear current. Using a simple PWIA\nmodel, cross sections and conversion factors are calculated for capture\nreactions p + n \u003e\u003e d + e^+ e^-, p + p \u003e\u003e 2He + e^+ e^- and p + 11B \u003e\u003e 12C + e^+\ne^- at proton energies of 100-200 MeV. The result is compared with a recent\nmeasurement of the conversion factor for p + 11B.",
