Pete,

I really don't think that there is a long list of scientists who are creationists, though there is a much longer list who are Christians. A.S. Eddington for instance, and later people like C.A. Coulson, John Polkinghorne, John Barrow, Jocelyn Bell-Burnell, George Ellis, Charles Townes. Of course the Vatican runs its own observatory, and the Jesuit order has many prominent scientists. But I can't think of a credible figure, at least in the physical sciences who is a young earth creationist.
