Comment on “Yakubovsky scheme to study the 4- and 5-nucleon systems in the case of alpha-state structure with spin-dependent nucleon–nucleon potentials” [Karbala International Journal of Modern Science 3, 287 (2017)]

The authors argue that 5He binding energies reported by E. Ahmadi Pouya and A. A. Rajabi [Karbala International Journal of Modern Science 3, 287 (2017)] are completely meaningless and should be discarded. The formalism of the paper has serious mistakes and the numerical results obtained from the coupled Yakubovsky integral equations in a three–dimensional scheme cannot be validated.
