// New physics list FTFP_BERT_ATL.
// This is a modified version of the FTFP_BERT physics list for ATLAS.
// The physics list FTFP_BERT_ATL has the transition between Bertini (BERT)
// intra-nuclear cascade model and Fritiof (FTF) string model in the
// energy region [9, 12] GeV (instead of [3, 6] GeV as in FTFP_BERT).
