The penetration probability is calculated within the WKB approximation.</p> <p><strong>Results:</strong> The α-decay half-lives of even-odd <sup>243</sup>Fm and <sup>245</sup>Fm isotopes and their daughter nuclei are obtained from the preformed cluster-decay model. These theoretically calculated half-lives are found to be in good agreement with the recent experimental measurements.</p> <p><strong>Conclusions:</strong> The novel result here is the applicability of the scaling factor within the PCM as a signature for shell/sub-shell closures in α-decay studies. As such, we have also demonstrated that N=137, 139 and Z=94 corresponding to <sup>231,233</sup>Pu could be shell/sub-shell closures. The least T<sub>1/2</sub> is found at <sup>243,245</sup>Fm which indicate their individual stability and α-decay as their most probable decay mode.</p>}, number={2}, journal={Journal of Nuclear Physics, Material Sciences, Radiation and Applications}, author={Joshua, T.
