Additional Info

In the fictional universe of Star Trek: The Next Generation, this element was apparently discovered and named. The episode "Rascals" depicted a "trans-periodic table," in a schoolroom set, which depicted element number 123 as being named jamesium, symbol Rj. The graphic was created by set artists, probably a homage to designer Richard D. James, and listed this element in the "gamma series."
