Abstract:
The four-body break-up d+11B → α+n reaction has been studied by simultaneous detection of α-α and α-n coincidences at two bombarding energies, 10.425 and 12.0 MeV, in order to obtain information about the decay properties of the excited states in 9Be. Measured spectra reveal the importance of sequential decay mechanisms in the reaction. The decay structure of low-lying levels in 9Be has been discussed.
