Differential cross sections of /sup 3/H(p,n)/sup 3/He and of /sup 6/Li(n,t)/sup 4/He by using triton beams between 5. 95 and 19. 15 MeV and a reevaluation of the p-T neutron production cross sections up to 12 MeV
Six angular distributions and the zero degree excitation function of the reaction /sup 1/H(t,n)/sup 3/He between 5.95 and 19.15 MeV were measured to provide back angle data for the /sup 3/H(p,n)/sup 3/He reaction between 2.0 and 6.4 MeV proton energy. Together with relative angular distributions at 2.22 and 3.00 MeV these data are the backbone of the new evaluation which gives appreciably higher angle yields than previous ones. Consistency of the data base is not very good resulting in maximum scale errors of +-4% and maximum shape error of the angular distributions of +-3%. Data of the reaction /sup 4/He(t,n/sub x/)/sup 6/Li can contribute to the knowledge of the cross section standard /sup 6/Li(n,t)/sup 4/He, the time-reversed reaction. New data for triton energies between 11.9 and 16.4 MeV (corresponding to neutron energies for N-/sup 6/Li between 2.3 and 5.3 MeV) are presented both for the population of the ground state in /sup 6/Li and the first excited state. In addition, data of the same reaction obtained in a previous experiment were revised above 12.8 MeV taking a 0.1% impurity of hydrogen into account.
