A study of the 15 C states was pursued in 2008 at the Catania INFN-LNS laboratory by the 13 C( 18 O, 16 O) 15 C reaction at 84 MeV incident energy. The 16 O ejectiles were detected at forward angles by the MAGNEX magnetic spectrometer. The spectra show several known low lying states up to about 7 MeV excitation energy as well as two unknown resonant structures at about 11.4 and 13.5 MeV. 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.
