Mass, Spectroscopy, and Two-Neutron Decay of 16Be

RADIOACTIVITY 16Be(2n) [from 1H(17B, 2p), E=277 MeV/nucleon]; measured decay products, En, In; deduced resonance energies, J, π, Q-value. Comparison with calculations incorporating the evolution of the wave function during the decay as a genuine three-body process reproduced the principal characteristics of the neutron-neutron energy spectra for both levels, indicating that the ground state exhibits a strong spatially compact dineutron component. The 15 cm thick liquid hydrogen target of MINOS, the BigRIPS fragment separator, the Radioactive Isotope Beam Factory of the RIKEN Nishina Center.
