Abstract: | Differential cross sections for the 11B(11B,10Be)12C proton transfer reaction leading to the 10Be(g.sO+12C(4.43 MeV) final channels have been measured at Ec.m. = 5.5 MeV by coincident detection of the 10Be and 12C nuclei. The integrated cross sections for the 10Be + 12C(4.43 MeV) channel have been obtained for incident energies between Ec.m. = 2.66 and 3.64 MeV from the yields of the 4.43 MeV γ-ray emitted in the 12C 4.43 MeV → g.s. transition. The cross-section magnitudes compare well with the DWBA calculations. The sub-barrier transfer cross sections exhibit an unusual energy dependence: their ratio to the total reaction cross section is decreasing with decreasing incident energy. |
