The inelastic scattering of deuterons, ${}_{}{}^3{}_{}{}^{}\mathrm{He}$, and $\alpha$ particles from ${}_{}{}^{63}{}_{}{}^{}\mathrm{Cu}$, ${}_{}{}^{65}{}_{}{}^{}\mathrm{Cu}$, and ${}_{}{}^{67}{}_{}{}^{}\mathrm{Zn}$ has been investigated to determine whether spin-dependent effects similar to those observed for protons were observable for these projectiles. The inelastic deuteron scattering shows an effect that is similar to, but stronger than, that seen for proton scattering. The angular distributions for ${\mathrm{½}}^{-}$ states are quite different from those for ${\frac{5}{2}}^{-}$ and ${\frac{7}{2}}^{-}$ states in ${}_{}{}^{63}{}_{}{}^{}\mathrm{Cu}$ and ${}_{}{}^{65}{}_{}{}^{}\mathrm{Cu}$. The inelastic ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ scattering exhibits no real structure in its angular distributions for any of the states, so no conclusions may be reached concerning spin-dependent effects for ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ scattering. The inelastic $\alpha$ scattering shows no spin-dependent effect. No definite theoretical explanation for these observations is apparent.
