# Comment on "Six-body bound system calculations in the case of effective $\alpha-$core structure" [Eur. Phys. J. Plus (2016) 131: 240]

## TL;DR

This paper critically examines a previous study on six-body bound systems, highlighting formal errors and issues with reproducibility that undermine the validity of its numerical results.

## Contribution

It provides a detailed critique of the methodology and numerical results of the prior work, emphasizing the importance of correct formalism and reproducibility in such calculations.

## Key findings

- The original calculations are flawed due to formal mistakes.
- The reported numerical results are not reproducible.
- The critique questions the validity of the previous study's conclusions.

## Abstract

The authors argue that the calculated $^6$He binding energies by the solution of the coupled Yakubovsky integral equation in a partial wave decomposition reported by E. Ahmadi Pouya and A. A. Rajabi [Eur. Phys. J. Plus (2016) 131: 240] are incorrect. The formalism of the paper has serious mistakes and the numerical results are not reproducible and cannot be validated.
