Identification of dielectron pair production in the exclusive npe+e− final state from quasifree n – p interactions using deuterium beams on proton target at kinetic beam energy of 1.25 GeV/u with the HADES spectrometer is presented. Comparison of the dielectron invariant mass distribution to the one measured in the p – p reaction shows a prominent enhancement in the high-mass region.
