Coupled-channel description for mirror mass-11 nuclei compared to shell-model structures
K. Amos, S. Karataglidis, L. Canton +2
The spectra of mass-11 nuclei are unusual, and so pose a challenge for theoretical models of their structure. The set of isobars range from being well bound to nucleon emission (11…

M. P. Carante, F. Barbaro, L. Canton +2
We have introduced a tool to describe in a simple and efficient way the outcomes of known nuclear reaction codes. It differs from the customary use where typically a specific singl…
Mass-15 nuclei and predicting narrow states beyond the proton drip line
P. R. Fraser, K. Amos, L. Canton +3
In a previous letter (Phys. Rev. Lett. 96, 072502 (2006)), the multi-channel algebraic scattering (MCAS) technique was used to calculate spectral properties for proton-unstable $^{…

We employ a collective vibration coupled-channel model to describe the nucleon-16O cluster systems, obtaining low-excitation spectra for 17O and 17F. Bound and resonance states of…
Structure of Al from a multi-channel algebraic scattering model based on mirror symmetry
P. R. Fraser, A. S. Kadyrov, K. Massen-Hane +5
The proton-rich nucleus Al has a ground state just 123 keV below the proton drip-line, and as a result comparatively little is known experimentally about its properties, as…
Importance of resonance widths in low-energy scattering of weakly-bound light-mass nuclei
P. R. Fraser, K. Massen-Hane, K. Amos +7
What effect do particle-emitting resonances have on the scattering cross section? What physical considerations are necessary when modelling these resonances? These questions are im…

A multi-channel algebraic scattering (MCAS) method has been used to solve coupled sets of Lippmann-Schwinger equations for +nucleus systems to find spectra of the compound syste…
Coupling to two target-state bands in the study of the n+22Ne system at low energy
P. R. Fraser, L. Canton, K. Amos +3
One theoretical method for studying nuclear scattering and resonances is via the multi-channel algebraic scattering (MCAS) formalism. Studies to date with this method have used a s…

A survey of known threshold excitations of mirror systems suggests a means to estimate masses of nuclear systems that are uncertain or not known, as does a trend in the relative en…
