Description
A recent paper presented high-quality implantation distributions and reflection coefficients (in the form of deposition rates, that is, D = 1 - R) for D on Be. At low energies, they show significantly higher reflection coefficients than SRIM, which is to be expected for a reactive ion-target pair.
Finding an appropriate D-Be potential would make this a very good benchmark for RustBCA's attractive-repulsive potential capabilities. They used a 3-body potential which the BCA cannot replicate; however, at the relevant ion energies (100s of eV) I suspect most of the physics can be adequately modeled with an attractive-repulsive pair potential instead.
