摘要：

A study of light neutron rich nuclei was pursued at the Catania INFN-LNS laboratory by the (O-18,O-16) reaction at 84 MeV incident energy on Be-9, B-11 and C-13 targets. The O-16 ejectiles were detected at forward angles by the MAGNEX magnetic spectrometer. The energy spectra of C-15 show several known low lying states up to about 7 MeV excitation energy as well unknown resonant structures at higher excitation energy. The strong excitation of these latter together with the measured width of about 2 MeV FWHM could indicate the presence of collective modes of excitation connected to the transfer of a correlated neutron pair. Similar features characterize the energy spectra of the Be-11 and B-13 nuclei.
