Excitation functions of inelastic and transfer channels in 12 C+12 C around Ec.m. = 32.5 MeV

A prominent and wide resonance centered at Ec.m. = 32.5 MeV has recently been found in the (02+, 02+) inelastic channel of the 12C+12C reaction. It has been suggested that it corresponds to a 6α-particle-chain state in 24Mg. In the present work we study 12C+12C excitation functions between center-of-mass energies of 30 and 35 MeV in steps of 250 keV for weakly populated outgoing channels. We present the inelastic channels to the states above the α-particle decay threshold, (01+,02+), (01+,31-), and (01+,414), and the one- and two-nucleon transfer channels. In the inelastic and the transfer channels we observe correlated intermediate-width structures at Ec.m. = 31, 32.5, and 33.5 MeV, whose widths are appreciably smaller than the width measured in the (02+,02+) channel. Our Ec.m. = 31, 32.5, and 33.5 MeV, whose widths are appreciably smaller than the width measured in the (02+,02+) channel. Our Ec.m. = 32.5 MeV angular distribution of the (01+,02+)channel exhibits oscillatory behavior and, unlike that of the (0+2, 0+2) channel, does not display enhancement around Θc.m. = 90 deg. Data were collected via the kinematic coincidence technique. For data reduction we use a novel approach allowing for the extraction of results on non-binary channels. (authors)
