The p-shell with one particle in the continuum Original Research Article

A continuum shell model is now available for p-shell nuclei with exactly the same important properties as a bound-state p-shell model calculation. This means that one can obtain all solutions that correspond to coupling one nucleon to the possible p-shell states of a bound-state calculation. The resulting coupled-channels solutions are antisymmetric and contain no spurious components. This model can be used to describe a very broad range of nuclear phenomena, from capture reactions at astrophysical energies, to knockout reactions at low energies, to nucleon scattering and charge exchange at intermediate energies. Example calculations are shown for the compound systems 7Be and 7Li. Here it is demonstrated that agreement between theoretical and experimentally determined elastic and inelastic cross sections and analyzing power values can be improved by coupling to all open channels.
