16Be

Ground-State Decay Evaluated Data



Measured Ground-State Γcm for 16Be

Adopted value: 0.32 ± 0.08 MeV (2024Mo02)
Measured Mass Excess for 16Be

Adopted value: 56.93 ± 0.13 MeV (2024Mo02)

Measurements
2003BA47: Be(40Ar, X); E = 140 MeV/nucleon; measured yields; deduced no evidence for 16Be.
2004TH15: Be(40Ar, X); E = 140 MeV/nucleon; measured fragment isotopic yields; deduced no evidence for 16Be.
2012SP01: 16Be(2n); measured decay products, En, In; deduced two-neutron separation energy. The energy resolution in this work was not sufficient enough to resolve the ground and first state of 16Be. Therefore, their results are for an unresolved ground+first excited states.
2013TH04: 16Be(2n); measured decay products, En, In; deduced decay energy spectra. Comparison with calculated two-neutron separation energies, T1/2, widths.
2024Mo02: 1H(17B,2p)16Be→14Be+2n; measured protons and the decay products with much higher statistics, and an improved energy resolution and detection efficiency (in comparison with those of (2012Sp01)); deduced decay energy spectra, level energies, resonance energies and widths for the ground and first excited state, and the mass excess for the ground state. Presented the results of a shell model calculation, and a 3-body decay modeling, which showed that both the ground and first excited state decays via dineutron emission. Comparison with the measured ground state mass excess is presented.
