Elerium was used in a computer game about UFO's as a name for element 115. So I think that is out. At this point I think we need to go the route that GSI did for element 112 and look for important scientists in the physics domain who have made an important contribution, even if not in the nuclear physics field per se. At this point LBNL (Berkelium, Californium, Americium), GSI (Darmstadtium, Hassium, Germanium is old), and Dubna (Dubnium) already have elements names after their facilities/towns/regions/countries and key scientists (Seaborgium, Mietnerium, Flerovium).. Yes i know Flerovium was technically named after the Flerov region to avoid controversy but that was the intent of the name.
