MEASUREMENT OF 14.7 MEV NEUTRON-ACTIVATION CROSS-SECTIONS FOR FUSION

The activation method has been used to measure 14. 7 MeV cross sections for 21 reactions which are important for fusion-energy applications. The results of this investigation are compared with corresponding recently evaluated cross-section values. Within the combined errors of the measured and evaluated results, the agreement is generally quite acceptable although some problem areas remain to be resolved. Significant improvements in the knowledge of the cross sections are achieved as a result of the present investigation for the reactions Ti(n, X)**4**7Sc, **5**9Co(n,p)**5**9Fe and **6**5Cu(n,p)**6**5Ni. In the case of **7Li(n,n prime t)**4He, the present measurement supports a recent evaluation in which a number of other n plus **7Li processes were simultaneously considered in conjunction with neutron-induced tritium production.
