Observation of Airy oscillation for the 16O+16O system at Elab = 145 MeV

Abstract We have measured elastic scattering angular distribution at E lab = MeV for the 16 O+ 16 O system, for which nuclear rainbow scattering has been observed recently at E lab = 350 MeV. Analysis of the present data shows that the observed dip at θ cm ≅ 54° and the modulated peak at θ cm ≅62° are an Airy minimum and an Airy maximum, respectively. We found several discrete sets of optical potentials which fit the data. One of them provides a real volume integral which agrees with the previously proposed energy dependence.
