Neutron radioactivity—Lifetime measurements of neutron-unbound states
A new technique to measure the lifetime � of a neutron-radioactive nucleus that decays in-flight via neutron emission is presented and demonstrated utilizing MonteCarlo simulations. The method is based on the production of the neutron-unbound nucleus in a target, which at the same time slows down the produced nucleus and the residual nucleus after (multi-) neutron emission. The spectrum of the ...
متن کاملComment on “ Neutron knockout of 12 Be populating neutron - unbound states in 11 Be ”
A recent paper [Phys. Rev. C 83, 057304 (2011)] used knockout from 12Be to populate two states near 3.9 MeV in 11Be and observed their neutron decay—but treated the two as a single state. The authors used a branching ratio for the upper state from an experiment that also did not separate the two states. Thus, their energy for 11Be(3.96 MeV) and the spectroscopic factor connecting it to 12Be(gs)...

متن کاملExperimental Studies of Unbound Neutron-rich Nuclei
The three-body description of two-neutron halo nuclei relies on the two-body interactions between the constituents. In order to provide constraints on calculations devoted to 14 Be and 17 B, the neutron unbound states of 13 Be and 16 B have been investigated by one-proton knockout. The experimental techniques and results are discussed here.
