The dipole strength distribution of He and decay characteristics
C. Lehr, T. Aumann, M. Duer +91
The weak binding and spatially extended neutron densities characteristic of drip-line nuclei give rise to a distinctive low-energy dipole response. The drip-line nucleus He is…

Direct observation of three-neutron emission from He and the search for the trineutron
S. W. Huang, C. Lenain, Z. H. Yang +107
Three-neutron emission from He has been directly measured for the first time, following neutron knockout from a He beam at 156 MeV/nucleon. A resonance-like structure at $2…

Photoneutron reactions on gold in the giant dipole resonance region: reaction cross sections and average kinetic energies of photoneutrons
I. Gheorghe, T. Ari-izumi, S. Goriely +12
In this work, we present new data on the Au photoneutron reactions in and above the giant dipole resonance region, obtained by using 8 to 39~MeV quasi-monochromatic -ra…
