Abstract

The 2H(α, αp)n reaction at 15–42 MeV is analysed by solving the Amado-Lovelace equations. Rank-one separable potentials with the Yamaguchi-type form factor are assumed in 12s, 12p and32p waves for the N-α subsystem and in the triplet s-wave for the n-p subsystem. The agreement with experiment is quite good in this energy region. The role of multiple-scattering terms is discussed. Interesting features of the reaction mechanism, such as the decay process through the 1+ resonance of 6Li, are found in this energy region. The triton transfer process at 15 MeV predicted by the modified impulse approximation is not found. The numerical method is discussed. It is shown that the rotated contour method causes no difficulties even when it is applied to breakup amplitudes.
