A semi-phenomenological model is constructed for the 6Li(p eta )7Be reaction using cluster decomposition models for the 6Li and 7Be nuclei. Wavefunctions derived from potential model descriptions of these two nuclei give rise to form factors which are too small to fit the new experimental data. On the other hand, form factors deduced from experimental data on the analogous 6Li(p, pi +)7Li and 6Li(d,p)7Li single-nucleon transfer reactions at high momentum transfers give a plausible description.
