Majorana tensor force for deuteron-nucleus interactions

By making use of a new generalized inversion technique for coupled-channel scattering, a new internucleus tensor interaction has been discovered. It f eatures a strong, short-range term which applies to even-parity channels. T he new tensor force seems to occur in several situations, and a microscopic particle exchange mechanism is suggested as an interpretation. Tensor inte ractions between composite particles are considered for d(4)He, dd, and NN treated as three-quark clusters. We have found that the tensor mixing of a nodal S wave and a nodeless D wave has some interesting new features that c an explain certain long-standing puzzles in the field.
