The reaction 2H(α,αp)n near threshold and excited states of 6Li

The reaction ²H(α,αp)n has been studied in a kinematically complete experiment between E_α=9.22 and 11.3 MeV (3.07 to 3.77 MeV in the CM system). Data at the highest energies are dominated by αp and αn final-state interactions and at the same time indicate the relevance of the broad state (J^π=2⁺, T=0) centered at 4.7 MeV in ⁶Li ignored heretofore in theoretical calculations. Possible effects due to three-body forces are discussed.
