We report on our latest experimental study of the 2H(ρ,γ)3He reaction in the energy range of interest for big-bang nucleosynthesis. The differential cross section at 135° and γ)-ray angular distributions were measured and compared with the results deduced from the latest ab-initio calculation. The astrophysical S-factor for the 2H(ρ,γ)3He reaction was obtained in the center-of-mass energy range E = 97-210 keV, and it is found to be in reasonable agreement with that predicted by the ab-initio calculation.
