New description of four-body breakup reaction
We present a novel method of smoothing discrete breakup cross sections
calculated by the method of continuum-discretized coupled-channels. The method
based on the complex scaling method is tested with success for Ni(,
) reaction at 80 MeV as an example of a three-body breakup reaction, and
applied to C(He, He) reaction at 229.8 MeV as a typical
example of a four-body breakup reaction. The new method does not need to derive
continuum states of the projectile in order to evaluate the breakup cross
section as a smooth factor of the excitation energy of the projectile. Fast
convergence of the breakup cross section with respect to extending the
modelspace is confirmed. For the He breakup cross section, the resonant
component is separated from the non-resonant one.Comment: 5 pages, 5 figure
