Nobel prizewinning British physicist and pioneer of quantum mechanics (5)

I believe the answer is:

dirac

(Other definitions for dirac that I've seen before include "Nobel Prize winner" , "constant originator" , "Scientist" , "English physicist" , "Paul -, physicist; I'd arc (anag.)" .)

I've seen this clue in The Times.
