    Abstract:
    A previous study of the ground-state transition of the 7Li(→p,γ)8Be reaction at energies of Ep(lab)=80-0 keV indicated the possibility of a large p-wave capture amplitude in this reaction. A similar p-wave component in the 7Be(p,γ)8B reaction could seriously affect the extrapolation used to obtain the astrophysical S factor. The present work examines this possibility by observing the closely related 7Li(→p,γ16.6)8Be* (2+, T=0+ 1) reaction with polarized protons at and below 80 keV. Experimental data for σ(θ)/A0 and Ay(θ) for capture to the third (16.6 MeV) excited state of 8Be are presented, and the implications discussed.
