IMPORTANT DIFFERENCES FROM RESULTS PREDICTED BY THE BUTLER THEORY HAVE BEEN OBSERVED IN ANGULAR DISTRIBUTIONS OF THE O- (D.P) O- REACTION, SPECIALLY WHEN THE INCIDENT DEUTERON ENERGY IS NEAR 1.7 MEV. IN THIS NEIGHBORHOOD, THE FORMATION OF THE COMPOUND NUCLEUS F- FROM THE FUSION OF O- AND H- IS POSSIBLE. TO DETERMINE THE POSITION OF THIS RESONANCE, THREE SERIES OF EXPOSURES HAVE BEEN CARRIED OUT AT THE VAN GRAAFF LABORATORY OF THE U.N.A.M., MEASURING THE INTENSITY OF PROTON GROUPS WITH A KNOWN SOLID ANGLE OBSERVED IN A SPECTROGRAPH AS A FUNCTION OF THE BOMBARDING ENERGY. THE DEFLECTOR AND SPECTOGRAPH MAGNETIC FIELDS WERE CHOSEN SO THAT THE FIRST EXCITED STATE OF O- REMAINDED ON THE SAME PLATE POSITION IN THE WHOLE SERIES OF EXPOSURES AND THAT THE GROUND STATE OF O- AND THE ELASTIC GROUPS OF C- AND O- WERE REGISTERED SIMULTANEOUSLY. A CONSTANT NUMBER OF ELASTIC DEUTERONS OF O- WAS TAKEN AS REFERENCE, AND THE OTHER INTENSITIES WERE CORRECTED ACCORDINGLY. A F- RESONANCE IS ESTABLISHED AT A 1.65- 0.03 MEV BOMBARDING ENERGY WHICH CORRESPONDS TO A LEVEL OF F- AT 8.99 MEV. THIS ALSO CONFIRMS WITH SOME WHAT BETTER APROXIMATION THE RESULT REPORTED PREVIOUSLY AT 9.0 MEV.
