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

We demonstrate, for the first time, successful S-matrix to potential invers ion for spin 1 projectiles with nondiagonal S-ll(j), yielding a T-R interac tion. The method is a generalization of the iterative-perturbative method. We present a test case indicating the degree of uniqueness of the potential . The method is adapted, using established procedures, into direct observab le to potential inversion, fitting sigma, iT(11), T-20, T-21, and T-22 for d + alpha scattering over a range of energies near 10 MeV. The T-R interact ion which we find is very different from that proposed elsewhere, both real and imaginary parts being very different for odd and even parity channels. [S0556-2813(99)05405-9].
