Intranuclear cascade model for alpha induced reactions at incident energies 50-150 MeV

The Intranuclear Cascade (INC) model with the inclusion of collective excitation, trajectory deflection and transmission coefficient successfully predicts low-energy (p, p'x) reactions over a wide range of targets. Taking into account nucleon correlations, INC model can predict fragment emissions considerably well up to ⁴He. In this report, INC has been improved to give accounts for α-particle induced reactions between 50-150 MeV of incident energies. Although JQMD and INCL are two widely used models for nucleus/light ion induced reactions in Particle and Heavy Ion Transport Code System, PHITS, both of them are known to show low predictive power for (α, α'x) reaction. As the consequence of including the correlation for incident α-particle, the predictive powers were improved significantly for (α, α'x) reactions. Although the direct reaction was ignored in this work, closer agreements with experiments were achieved for other α-induced reactions. (author)
