The {sup 2}H({ital d},{gamma}){sup 4}He reaction is studied at center-of-mass energies below 500 keV, where it is dominated by the {ital E}2 transition from the {sup 5}{ital S}{sub 2} continuum state to the ground state of the {alpha} particle. Both the {sup 5}{ital S}{sub 2} continuum and the ground states are calculated with the variational Monte Carlo method using the realistic Argonne-{ital v}{sub 14} two-nucleon and Urbana model-VII three-nucleon interactions. A qualitative agreement with the observed cross section is obtained. This reaction can proceed only through the {ital D} states in the deuteron and/or in the {alpha} particle. It is found that, depending upon the continuum wave function, the contributions of the deuteron and {alpha}-particle {ital D} states can either add to produce a large cross section, or cancel. The reaction is thus very sensitive to the continuum wave function.
