High-lying excited states in ^10Be from the ^9Be（^9Be,^10Be）^8Be reaction

A transfer-reaction experiment of ^9Be（^9Be,^10Be）^8Be was performed at a beam energy of 45 Me V.Excited states in ^10Be up to 18.80 Me V are produced using missing mass and invariant mass methods.Most of the observed high-lying resonant states,reconstructed from theα＋~6He and t＋~7Li decay channels,...

More Information
Summary:A transfer-reaction experiment of ^9Be（^9Be,^10Be）^8Be was performed at a beam energy of 45 Me V.Excited states in ^10Be up to 18.80 Me V are produced using missing mass and invariant mass methods.Most of the observed high-lying resonant states,reconstructed from theα＋~6He and t＋~7Li decay channels,agree with the previously reported results.In addition,two new resonances at 15.6 and 18.8 Me V are identified from the present measurement.The 18.55 Me V state is found to decay into both the t ＋ ~7Lig：s： and t ＋ ~7Li？（0.478 MeV） channels, with a relative branching ratio of 0：93 ± 0：33. Further theoretical investigations are encouraged to interpret this new information on cluster structure in neutron-rich light nuclei.
