| Abstract: | The Wallace Fourier-Bessel expansion of the scattering amplitude is generalised to the case of the scattering of a spin-one particle from a potential with a single tensor coupling as well as central and spin-orbit terms. A generating function for the eikonal-phase (quantum) corrections is evaluated in closed form. For medium-energy deuteron-nucleus scattering, the first-order correction is dominant and is shown to be significant in the interpretation of analysing power measurements. This conclusion is supported by a numerical comparison of the eikonal observables, evaluated with and without corrections, with those obtained from a numerical resolution of the Schrödinger equation for d-58 Ni scattering at incident deuteron energies of 400 and 700 MeV.Received: 4 December 2003, Published online: 10 August 2004PACS: 03.65.Nk Scattering theory - 24.70. + s Polarization phenomena in reactions - 25.10. + s Nuclear reactions involving few-nucleon systems - 25.40.Hs Transfer reactionsM.W.
