Sažetak
The alpha(10Be, alpha)10Be resonant scattering reaction has been measured at nine 10Be beam energies from 25 to 48 MeV, scanning out resonances in 14C from excitation energies of 13 to 24 MeV. Angular distribution measurements were used to assign the spin and parity of 5- to resonances at Ex=18.82(2) MeV and 19.67(2) MeV and 6+ at Ex= 20.80(2) MeV. The data also strongly indicate a 3- resonance at 17.32(2) MeV. An R-matrix analysis has been performed for the excitation energy range 16.5 to 22 MeV. The data are discussed in terms of cluster bands in 14C.
