A study of the C-15 states was pursued in 2008 at the Catania INFN-LNS laboratory by the (13)c(O-18,O-16)C-15 reaction at 84 MeV incident energy. The O-16 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.

Abstract
A study of the C-15 states was pursued in 2008 at the Catania INFN-LNS laboratory by the (13)c(O-18,O-16)C-15 reaction at 84 MeV incident energy. The O-16 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.File in questo prodotto:
