Spin 1 inversion: a Majorana tensor force for deuteron alpha scattering

We demonstrate, for the first time, successful S-matrix to potential inversion for spin one projectiles with non-diagonal S j llyielding a TR interaction. The method is a generalization of the iterative-perturbative, IP, method. We present a test case indicating the degree of uniqueness of the potential. The method is adapted, using established procedures, into direct observable to potential inversion, fitting �, iT11, T20, T21 and T22 for d + alpha scattering over a range of energies near 10 MeV. The TR interaction which we find is very different from that proposed elsewhere, both real and imaginary parts being very different for odd and even parity channels.
