Analyzing Powers of Continuum Spectra of ReactionsSi28,Ni58,Bi209(ppol, p′X) and (ppol, dX) at 65 MeV

Analyzing powers of the continuum energy spectra from the reactions ${}_{}{}^{28}{}_{}{}^{}\mathrm{Si}$, ${}_{}{}^{58}{}_{}{}^{}\mathrm{Ni}$, ${}_{}{}^{209}{}_{}{}^{}\mathrm{Bi}$($p_{\mathrm{pol}}, p^{\prime }X$) and ($p_{\mathrm{pol}}, \mathrm{dX}$) at 65 MeV have been measured. The analyzing powers of the continuum spectra were found to be small at forward angles and to be very large and positive at backward angles. These features indicate the importance of the spin-dependent interaction in the understanding of the continuum spectra.
