59Co($\vec p$,α) reaction at 100 MeV incident energy – statistical multistep direct reaction into the continuum of outgoing energies

“…This is a general feature of multistep calculations, as was also found in our previous work [12][13][14]. Although the actual step which is dominant at a specific emission energy only influences the shape of Figure 1.…”

Interplay between multiple intranuclear scattering and pickup in proton-induced emission of3He into the continuum

“…The observed incident energy dependence of the (p, 3 He) reaction to discrete final states explains why the characteristic signature of the multistep-pickup process in the continuum disappears as the incident energy increases beyond about 160 MeV.…”

“…1. This way in which the multiple scattering manifests itself appears to be independent of target mass over a large range [1][2][3], although detailed differences, which are correctly reproduced by the theory, are observed.…”

“…Recently proton-induced emission of 3 He into the continuum has been clearly linked to twoparticle pickup as a final process in an intranuclear multistep chain [1][2][3]. A typical example [3] of how multiple intranuclear N-N collisions, which precede pickup of a neutron-proton pair to form an emitted 3 He particle, effect the analyzing power is shown in Fig.…”
