Abstract: | We present for the first time evidence for the existence of a dynamically refracted primary bow for Be-9 + O-16 scattering. This is demonstrated through the use of coupled channel calculations with an extended double folding potential derived from the density-dependent effective two-body force and precise microscopic cluster wave functions for Be-9. The calculations reproduce the experimental Airy structure in Be-9 + O-16 scattering well. It is found that coupling of a weakly bound 9Be nucleus to excited states plays the role of a booster lens, dynamically enhancing the refraction over the static refraction due to the Luneburg lens mean field potential between the ground states of Be-9 and O-16. |
