Calculation of breakup cross section for four-body breakup reaction systems

摘要

We present a new method of smoothing discrete breakup cross sections calculated by the method of continuum-discretized coupled-channels. In the four-body breakup reaction of ~(12)C(~6He, nn~4He) at E_(in) = 229.8 MeV, the continuous breakup cross section is evaluated as a function of the excitation energy of ~6He. Convergence of the cross section with respect to extending the modelspace is also confirmed.
