Abstract

Using the 50 kV LUNA accelerator facility at the Gran Sasso underground laboratory we measured, with an accuracy of the order of 10%, the d(p, γ)3He cross section from 22 down to 2.5 keV c.m. energy, well below the solar Gamow peak. The experimental set-up was based on a large solid angle, segmented BGO detector and a renewed windowless gas target. The astrophysical S(E) factor within the Gamow peak is in fair agreement with the value of one of the existing extrapolations of data at higher energies.
