TITLE=/SYMMETRIC-TO-ASYMMETRIC MASS RATIOS FOR PROTON-INDUCED FISSION
OF 232TH AND 238U/;
PURPOSE=/MOST SYMMETRIC-TO-ASYMMETRIC (N(S)/N(A)) OR PEAK-TO-VALLEY
(P/V) RATIOS OF FISSION FRAGMENTS AS A FUNCTION OF INCIDENT
PROTON ENERGY SHOW DISTINCT BREAKS AT CERTAIN ENERGIES, THAT
HAVE BEEN INTERPRETED AS THE OPENING OF ANOTHER REACTION
CHANNEL, SUCH AS FISSION FLLOWING EMISSION OF ONE OR TWO
NERTRONS(SECOND- OR THIRD-CHANCE FISSION). THE OBJECTIVE OF
THE PRESENT STUDY WAS TO DETERMINE THE EXISTENCE AND POSITION
OF SUCH BREAKS WITH A MORE SENSITIVE DETECTOR SYSTEM THAN WAS
PREVIOUSLY USED./;
