PLATYPUS: a code for fusion and breakup in reactions induced by weakly-bound nuclei within a classical trajectory model with stochastic breakup

TL;DR

PLATYPUS is a Fortran-90 program that models fusion and breakup processes in reactions involving weakly-bound nuclei using a classical trajectory approach with stochastic breakup, aiding in understanding fusion dynamics near the Coulomb barrier.

Contribution

It introduces a self-contained code that accurately simulates fusion and breakup in weakly-bound nuclear reactions with detailed observables.

Findings

Calculates complete and incomplete fusion cross sections.

Provides angular momentum distribution of fusion events.

Generates breakup observables like angles and energy distributions.

Abstract

A self-contained Fortran-90 program based on a classical trajectory model with stochastic breakup is presented, which should be a powerful tool for quantifying complete and incomplete fusion, and breakup in reactions induced by weakly-bound two-body projectiles near the Coulomb barrier. The code calculates complete and incomplete fusion cross sections and their angular momentum distribution, as well as breakup observables (angle, kinetic energy and relative energy distributions).
