Summary: | The isomeric state of \(^{16}\)N was studied using the \(^{16}\)N\(^{g,m}\)(\(d\),\(^3\)He)~proton-removal reactions at \mbox{11.8~MeV/\(u\)} in inverse kinematics. The \(^{16}\)N beam, of which 24% was in the isomeric state, was produced using the ATLAS in-fight facility and delivered to the HELIOS spectrometer, which was used to analyze the \(^{3}\)He ions from the (\(d\),\(^{3}\)He) reactions. The simultaneous measurement of reactions on both the ground and isomeric states, reduced the systematic uncertainties from the experiment and in the analysis. A direct and reliable comparison of the relative spectroscopic factors was made based on a Distorted-Wave Born Approximation approach. The experimental results suggest that the isomeric state of \(^{16}\)N is an excited neutron-halo state. The results can be understood through calculations using a Woods-Saxon potential model, which captures the effects of weak-binding. |
