Hello,

for ions below 1 keV nuclear fragmentation cross section is zero for ions due to the Coulomb barrier. So, if I correctly understand your e-mail, you do not need hadronic physics at all - any Physics List (except LBE) can be used. Low energy ions are treated better in EMY, EMZ, LIV and PEN electromagnetic options, for example, you can use FTFP_BERT_LIV, QBBC_EMY,.....

You should also take into account, that our models for ions with energy below 1 keV are approximate, ions will have tendency to stop in 1 step. One can suspect that any reference physics list will not work well and some custom physics configuration will be needed.
