Abstract
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 product ion of e(+)e(-) pairs are studied, and results for cross sections and respo nse functions are presented. The effect of time-like form factors on the di lepton cross sections is investigated as well. (C) 1998 Elsevier Science B. V. All rights reserved.
