A study of (n, d) and (n, t) reactions on 7Li

Charged-particle spectra from neutron irradiation of 7Li were measured at several angles. The angular distribution of deuterons from the 7Li(n, d)6He(g.s.) transition was compared with the DWBA prediction. The absolute value of the cross section was in satisfactory agreement, but the shape of the measured angular distribution was not well reproduced by the calculations. The angular distribution of tritons in the peak of the spectra was compared with the DWBA prediction for the pickup of two nucleons. The shape of the angular distribution was reproduced reasonably well. A discrepancy in the absolute value was interpreted as a consequence of quasi-free n-t scattering.
