Hello, I just notice that feff6 in Athena from the last versions of Demeter (including the 0.9.26) did not accept Z value above 94 (Pu) anymore. I wanted to fit AM L3 data and got error message from FEFF that it was not possible. Changing Am Z to 94 solves the problem. Is it possible to get Am (Z=95) and Cm (Z=96) implemented in feff again? I am aware that using Z=94 for simulation of Am and Cm will likely yields similar results, by just replacing the Z in the atom output. But if it is possible without too much effort it will be nice to have. Thanks a lot. Cheers Kathy Dardenne
