Abstract

We present evidence for the nuclear ripples superimposed on the Airy structure of the nuclear rainbow, which is similar to the meteorological rainbow. The mechanism of the nuclear ripples is also similar to that of the meteorological rainbow, which is caused by the interference between the externally reflective waves and refractive waves. The nuclear ripple structure was confirmed by analyzing the elastic angular distribution in 16^{16}O+12^{12}C rainbow scattering at ELE_L=115.9 MeV using the coupled channels method by taking account of coupling to the excited states of 12^{12}C and 16^{16}O with a double folding model derived from a density-dependent effective nucleon-nucleon force with realistic wave functions for 12^{12}C and 16^{16}O. The coupling to the excited states plays the role of creating the external reflection.
