Breakup-fusion analysis of continuum spectra of α- and h-induced reactions

Calculations are performed for the continuum spectra of protons, deuterons, and tritons emitted from α- and h-induced reactions of the breakup type. It is shown that the sum of the elastic breakup and breakup-fusion contributions fit the major parts of the observed spectra, except for the (α, p) case, where the theory underestimates experiment. It is then shown that the contributions from the quasi-elastic channel, in which T = 1 dinucleons are created, account for most of the remaining (α,p) cross section. The quasi-elastic breakup and breakup-fusion are further shown to nicely fit two-proton coincidence data. The question of radial regions where the various modes of reactions dominantly occur is clarified, making it possible to understand why the various modes of reactions explain certain portions of the observed spectra
