The {sup 3}He(d,p){sup 4}He reaction has been studied from E{sub c.m.}=600 keV down to astrophysical energies by means of the 'Trojan horse' method using the {sup 6}Li({sup 3}He,p{alpha}){sup 4}He three-body reaction at E{sub lab}=5 and 6 MeV. Coincidence spectra were measured in kinematic conditions favoring the quasifree {sup 3}He+{sup 2}H process. The bare astrophysical factor S{sub b}(E) for the {sup 3}He(d,p){sup 4}He reaction was extracted from the three-body cross section in the modified plane-wave Born approximation. Comparison with the S{sub b} extrapolation from the free two-body data is presented. The independent estimate of the screening potential as obtained with the present work seems to confirm the theoretical adiabatic limit.
