Production of e(+)e(-) pairs in proton-deuteron capture to He-3

The process p + d He-3 + gamma * at intermediate energies is described using a covariant and gauge-invariant model, and a realistic pd(3)He vertex, Both photodisintegration of He-3 and proton-deuteron capture with production of e(+)e(-) pairs are studied, and results for cross sections and response functions are presented. The effect of time-like form factors on the dilepton cross sections is investigated as well
