Abstract

We investigate the contribution of the 22+ resonance in He6 to observables via analysis of the He6(p, p′) reaction by using the continuum-discretized coupled channels method combined with the complex-scaling method. In this Rapid Communication, we obtain the 22+ state with the resonant energy 2.25 MeV and the decay width 3.75 MeV and analyze contributions of resonances and nonresonant continuum states to the cross section separately. It is found that the 22+ state plays an important role in the energy spectrum. Furthermore, contributions of nonresonant continuum states are also important to clarify the properties of the 22+ state.
