Abstract: Using the folding procedure, we investigate the bound state of the Ω + α system. Previous theoretical analyses have indicated the existence of a deeply bound ground state, which is attributed to the strong Ω -nucleon interaction. By employing well-established parameterizations of nucleon density within the alpha particle, we performed numerical calculations for the folding Ω - α potential. Our results show that the V Ω α (r) potential can be accurately fitted using a Woods-Saxon function, with a phenomenological parameter R = 1.1 A 1 / 3 ≈ 1.74 fm ( A = 4 ) in the asymptotic region where 2 < r < 3 fm. We provide a thorough description of the corresponding numerical procedure. Our evaluation of the binding energy of the Ω + α system within the cluster model is consistent with both previous and recent reported findings. To further validate the folding procedure, we also calculated the Ξ - α folding potential based on a simulation of the ESC08c Y-N Nijmegen model. A comprehensive comparison between the Ξ - α folding and Ξ - α phenomenological potentials is presented and discussed. [ABSTRACT FROM AUTHOR]
