Investigation of contributions of the $2_2^{+}$ resonance in ${}^6$He via analysis of ${}^6$He($p$, $p^{\prime }$)

Abstract

We investigate the contribution of the $2_2^{+}$ resonance in ${}^6$He to observables via analysis of the ${}^6$He($p,p^{\prime }$) reaction by using the continuum-discretized coupled channels method combined with the complex-scaling method. In this study, we obtain the $2_2^{+}$ state with the resonant energy 2.25 MeV and the decay width 3.75 MeV and analyse contributions of resonances and nonresonant continuum states to the cross section separately. It is found that the $2_2^{+}$ state plays an important role in the energy spectrum. Furthermore, contributions of nonresonant continuum states are also important to clarify the properties of the $2_2^{+}$ state.
