A novel scheme for measuring the cross section of the 7Be(p,gamma)8B reaction, the major source of high energy neutrinos from t he sun, is presented. The scheme involves a strictly uniform particle beam and overcomes some of the recognized experimental uncertainties of previous measurements. A new measurement of sigma[7Li(d,p)8Li] has been carried out using this setup,and the present value of sigma[7Li(d,p)8Li] = 155(8) mbarn at the top of the E_d(lab.)= 776 keV resonance is compared to previous measurements. A new issue regarding both the (d,p) and (p,gamma) reactions has been examined: reaction-product nuclei which are backscattered out of the target. Measurements and simulations carried out in the course of this investigation are presented and discussed in the context of possible effects on the measured cross sections of these reactions.
