Abstract
The nucleus 133Sn83, with one single neutron outside doubly-magic 132Sn, was studied at the Radioactive Isotope Beam Factory at RIKEN. The excited states of 133Sn were populated via one-neutron knockout from a 134Sn beam on a carbon target at relativistic energies. Besides the γ rays emitted following the decay of known neutron single-particle states, additional γ strength above the neutron separation energy was observed for the first time. It has been interpreted as evidence for a competition between γ-ray and neutron emission in the decay of neutronunbound states in 133Sn.
