⁶Li structure information from ²H(α,α)²H scattering

In this study, we investigate low-energy elastic scattering of 4He+2 H using an effective two-body clusterisation model. We solve the Lippmann-Schwinger equations assuming that coupling effects between channels involving the 2H bound 3S1 state and those of the virtual 1S0 state are negligible. Two calculations have been performed; one using a potential that best recreates the 6Li spectrum, and the other to best recreate the low-energy elastic cross section, for which there is a large amount of experimental data. The potential so prescribed in each case is used for both the 3S1 and 1S0 channel sets. These calculations show that an effective two-body model suffices to explain many features of the data.
