[en] α-spectra induced by 72 MeV polarized protons on the target nuclei 12C, 27Al, 58Ni, 90Zr and 209Bi have been measured. Two-stage model has been applied to describe this inclusive (p-vector, αx) reaction. Experimental data for the analyzing power in the continuum of this reaction are compared with predictions of quasi-free scattering model. (L.I.)
