\begin{document}$Y=\Xi, \Omega$\end{document}, and \begin{document}$\alpha$\end{document} using a single-folding potential method, based on a separable Y-nucleon potential. The potentials \begin{document}$\Xi+\alpha$\end{document} and \begin{document}$\Omega+\alpha$\end{document} are accordingly obtained using the ESC08c Nijmegens \begin{document}$\Xi N$\end{document} potential (in \begin{document}$^{3}S_{1}$\end{document} channel) and HAL QCD collaboration \begin{document}$\Omega N$\end{document} interactions (in lattice QCD), respectively. In deriving the potential between Y and \begin{document}$\alpha$\end{document}, the same potential between Y and N is employed. The binding energy, scattering length, and effective range of the Y particle on the alpha particle are approximated by the resulting potentials. The depths of the potentials in \begin{document}$\Omega \alpha $\end{document} and \begin{document}$\Xi \alpha $\end{document} systems are obtained at \begin{document}$-61$\end{document} MeV and \begin{document}$-24.4$\end{document} MeV, respectively. In the case of the \begin{document}$\Xi \alpha$\end{document} potential, a fairly good agreement is observed between the single-folding potential method and the phenomenological potential of the Dover-Gal model. These potentials can be used in 3-,4- and 5-body cluster structures of \begin{document}$ \Omega$\end{document} and \begin{document}$\Xi$\end{document} hypernuclei."> Simple Woods-Saxon-type form for Ω<i>α</i> and Ξ<i>α</i> interactions using folding model -
