THE GOAL OF THIS PROPOSAL IS TO USE CORRELATED NEUTRON-HIGH-RESOLUTION ¿-RAY DATA TO IMPROVE OUR KNOWLEDGE OF (N,XN’¿) REACTION CROSS SECTIONS ON NUCLIDES OF INTEREST TO STEWARDSHIP SCIENCE. THEIR PROGRAM WILL UTILIZE THE GAMMA ENERGY NEUTRON ENERGY SPECTROMETER FOR INELASTIC SCATTERING (GENESIS) ARRAY BUILT AT THE LBNL 88-INCH CYCLOTRON TO PERFORM THE FIRST-EVER NEUTRON-HIGH-RESOLUTION GAMMA COINCIDENT MEASUREMENTS ON THE NUCLEI OF INTEREST. THEY WILL UTILIZE THE INTENSE THICK TARGET DEUTERON BREAK-UP NEUTRON SOURCE AT THE LAWRENCE BERKELEY NATIONAL LABORATORY 88-INCH CYCLOTRON TO COVER THE ENTIRE ENERGY RANGE OF INTEREST TO STOCKPILE STEWARDSHIP WHILE SIMULTANEOUSLY ALLOWING FOR ENERGY-INTEGRAL VALIDATION MEASUREMENTS OF NON-ELASTIC CHANNELS VIA POST-IRRADIATION ACTIVATION. ONE GRADUATE AND ONE UNDERGRADUATE STUDENT WORKING WITH THE PI AND OTHER MEMBERS OF THE BAY AREA NUCLEAR DATA GROUP WILL ANALYZE THE DATA FROM THESE EXPERIMENTS. THEY WILL THEN WORK WITH REACTION MODELING EXPERTS AT LANL AND LLNL TO ITERATIVELY PRODUCE A BANK OF MODELED COINCIDENT EVENTS THAT WILL BE PROPAGATED THROUGH A BENCHMARKED SIMULATION OF GENESIS AND COMPARED TO MEASURED DATA. THE VARIANCE BETWEEN THE MEASURED AND MODELED DATA RESPONSE WILL THEN BE USED TO PROVIDE A SELF-CONSISTENT MEASUREMENT SET OF CROSS SECTIONS THAT ARE WELL-SUITED TO THE PRODUCTION OF A NEW REACTION EVALUATION. A TOTAL OF THREE NUCLEI OF INTEREST TO STEWARDSHIP SCIENCE WILL BE STUDIED: 27AL, 93N AND, 209BI OR 169TM.
