Polarized neutron scattering data for the nuclei ²⁷Al, ^natCr, ^natCu, ⁸⁹Y, ^natW, ^natPb, ²⁰⁹Bi, ²³²Th and ²³⁸U were analyzed in terms of spherical, coupled channels and microscopic optical model potentials. The measurements at typical 7.75 MeV neutron energy were performed at the Stuttgart SCORPION facility.

KEYWORDS: Diff. cross section, analyzing power, spherical, coupled channels, microscopic optical model
