Abstract
It is shown that the neutron polarization by electromagnetic scattering at small scattering angles near an -wave resonance may be observable at larger angles than considered previously. The angle increase possible is most pronounced at the interference minimum of the total-cross-section curve below the resonance energy. The nuclear spin-orbit polarization is also considered, and it is shown that for small-angle scattering and low energy and an assumed typical interaction strength this polarization is much less than the polarization arising from the electromagnetic spin-orbit interaction. This conclusion may be modified if the spin-orbit interaction strength is larger than that assumed because of a possible resonance behavior in the spin-flip scattering. The resonance behavior is indicated by a phase-shift analysis of the scattering, which also leads to the plane-wave Born-approximation result (nonresonant) under special conditions.
