le o eceived June 1968 ifferential cross sections and asymmetries for 5® MeV proton scattering from vibrational states in ® D , r®n and ""C have been analysed using a collective-modrl interaction obtained by deforming the entire optical potential. The strong single-phonon states (2+ and 3-) are well described, while predictions for weak two-phonon states are less successful .
