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…
\textit{Ab initio} study of spectroscopic factors in K and neighboring isotones
P. Y. Wang, M. R. Xie, Q. Yuan +2
A recent \(^{47}\text{K}(d,pγ)^{48}\text{K}\) transfer reaction measurement has identified new excited states in \(^{48}\text{K}\) and extracted the corresponding spectroscopic fa…
How Threshold Effects in Spectroscopic Factors Influence Heavy-Ion Knockout Reactions
M. R. Xie, J. G. Li, C. A. Bertulani +3
A two-decade-old puzzle in heavy-ion one-nucleon knockout reactions is the strong correlation between the reduction factor and the Fermi surface asym…
The role of the overlap function in describing angular distributions of single-nucleon transfer reactions
M. R. Xie, J. G. Li, N. Keeley +2
Single-nucleon transfer reactions offer a valuable way to probe nuclear structure. We explore the effect of directly introducing overlap functions computed using the Gamow shell mo…
Gamow shell model study of the 17Ne(p, p) reaction and of isospin symmetry breaking in 18Na
N. Chen, J. G. Li, K. H. Li +3
The unbound nucleus 18Na, acting as an intermediate nucleus in the sequential decay of 19Mg, is situated beyond the proton drip line. We employ the coupled-channel Gamow shell mode…
Quenching of single-particle strength inferred from nucleon-removal transfer reactions on C
Y. C. Jiang, J. Chen, B. P. Kay +24
The difference in the proton and neutron separation energies () of the weakly bound C ground state is -19.86 MeV, an extreme value. Data from intermediate-energy heavy-…
