by Hofsäss et al. introduces a new BCA code, IMINTDYN , and performs a specific experimental validation (they call it a verification) of scattering. IMINTDYN includes dynamic vacancy generation and recombination, and some sort of method for scattering from vacancies - these should be investigated as possible additions to RustBCA if they offer significant improvements.
