  We present for the first time evidence for the existence of a dynamically
refracted primary bow for $^{9}$Be+$^{16}$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 $^{9}$Be. The calculations
reproduce the experimental Airy structure in $^{9}$Be+$^{16}$O scattering
well.It is found that coupling of a weakly bound $^{9}$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 $^{9}$Be and $^{16}$O.
