Angular distributions have been measured for the elastic, inelastic, one- and two-neutron transfer reactions for the system 18O+ 18O at c.m. energies ranging from 10.0 to 18.0 MeV, at c.m. angles between 90° and 125°. The inelastic scattering data were analyzed assuming a collective excitation mechanism and with a coupled channels approach. In order to obtain a good fit it was necessary to include a hexadecapole deformation. The one- and two-neutron transfer reactions were analyzed in terms of a single-step finite-range plus recoil DWBA theory.
