Abstract

We present for the first time evidence for the existence of a dynamically refracted primary bow for 9^{9}Be+16^{16}O 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 9^{9}Be. The calculations reproduce the experimental Airy structure in 9^{9}Be+16^{16}O scattering well.It is found that coupling of a weakly bound 9^{9}Be nucleus to excited states plays the role of a booster lens, dynamically enhancing the refraction over the {\it static} refraction due to the Luneburg lens mean field potential between the ground states of 9^{9}Be and 16^{16}O.
