Singlet deuteron production in the deuteron-alpha breakup reaction at 7 MeV
The cross section and one tensor analyzing power have been measured in kinematically-complete geometry for the breakup of deuterons on alpha particles at 7 Mev bombarding energy. Kinematic conditions were chosen to observe production of the isospin-violating single deuteron, d*, state. Comparisons with two three-body calculations were made to investigate treatment of Coulomb effects in the calculations. One treats Coulomb effects only as a final-state-interaction factor, while the second incorporates these effects in an approximate way into the three-body calculation. The latter calculation appears to reproduce the measured results better than the former. There is convincing evidence for significant singlet deuteron production in the breakup reaction at low energy. An improvement in the manner in which the Coulomb interaction is treated in the three-body calculations is needed to provide good quantitative agreement with experiment.
