Differential cross sections of the reaction 4 He(t,n) 6 Li, including some data of the first and second excited states of 6 Li, were measured and compared with an R-matrix analysis of previous data in the 7 Li system. Excellent agreement is observed for the angular distribution at the 0.24-MeV resonance of n-6 Li, and the shape of the angular distribution for 4 Hs(t,n,) 6 Li at 12.9 MeV is predicted qualitatively by the R-matrix analysis. However, for neutron energies greater than 0.5 MeV for 6
more » ... Li(n,t)*He the zero-degree excitation function is consistently lower (about 30%) in the R-matrix analysis.
