Excitation functions of inelastic and transfer channels in 12C+ 12C between Ec.m. = 30 and 60 MeV

Abstract

The 12C+ 12C excitation functions have been studied for unbound inelastic channels at centre-of-mass energies between 35 and 45 MeV and for transfer channels between 30 and 60 MeV, in steps of 250 keV. Results are presented for the inelastic channels (0+1,0+2), (0+1,3-1) and (0+1,4+1) to the unbound 12C states above the -particle decay threshold and for the one- and two-nucleon transfer channels. Intermediate-structure resonances tend to disappear above Ec.m. = 35 MeV, while a broad structure becomes a general feature of the interaction at higher energies.
