Nobelist Joliot-Curie (5)
I believe the answer is:
irene
'nobelist joliot-curie' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for irene that I've seen before include "Peaceful girl" , "One can find a girl in Ree" , "Girl's name (meaning Peace)" , "Greek godess of peace" , "- - Handl, actress" .)
