Calculations of polarized neutron-polarized [sup 3]He scattering are presented for the transverse and longitudinal total cross-section differences [Delta][sigma][sub [ital T]] and [Delta][sigma][sub [ital L]] in the energy range [ital E][sub [ital n]]=0.1 to 10 MeV. Predictions made from phase-shift analyses, [ital R]-matrix analysis, and a multichannel resonating group-model calculation are compared. The predictions are in qualitative agreement and show that polarized neutron-polarized [sup 3]He scattering is sensitive to the level structure of [sup 4]He in the excitation energy range 20--30 MeV.
