Slope parameters determined from CREX and PREX2 (published in Results in Physics)

[Background] Very lately, the CREX group presents a skin value $\mathrm{\Delta }{R}_{\mathrm{s}\mathrm{k}\mathrm{i}\mathrm{n}}^{48}(\mathrm{C}\mathrm{R}\mathrm{E}\mathrm{X})=0.121\pm 0.026(\mathrm{e}\mathrm{x}\mathrm{p})\pm 0.024(\mathrm{m}\mathrm{o}\mathrm{d}\mathrm{e}\mathrm{l})=0.071\sim 0.171$~fm. Meanwhile, the PREX group reported a skin value $\mathrm{\Delta }{R}_{\mathrm{s}\mathrm{k}\mathrm{i}\mathrm{n}}^{208}(\mathrm{P}\mathrm{R}\mathrm{E}\mathrm{X}2)=0.283\pm 0.071=0.212\sim 0.354$~fm. In our previous paper, we determined both the $L$–$\mathrm{\Delta }{R}_{\mathrm{s}\mathrm{k}\mathrm{i}\mathrm{n}}^{48}$ relation and the $L$–$\mathrm{\Delta }{R}_{\mathrm{s}\mathrm{k}\mathrm{i}\mathrm{n}}^{208}$ one, using 206 EoSs, where $L$ is a slope parameter. [Purpose] We determine $L$ from $\mathrm{\Delta }{R}_{\mathrm{s}\mathrm{k}\mathrm{i}\mathrm{n}}^{48}(\mathrm{C}\mathrm{R}\mathrm{E}\mathrm{X})$ and $\mathrm{\Delta }{R}_{\mathrm{s}\mathrm{k}\mathrm{i}\mathrm{n}}^{208}(\mathrm{P}\mathrm{R}\mathrm{E}\mathrm{X}2)$, using 207 EoSs. [Results] The $\mathrm{\Delta }{R}_{\mathrm{s}\mathrm{k}\mathrm{i}\mathrm{n}}^{48}(\mathrm{C}\mathrm{R}\mathrm{E}\mathrm{X})$ yields $L(\mathrm{C}\mathrm{R}\mathrm{E}\mathrm{X})=0\sim 51$~MeV and the $\mathrm{\Delta }{R}_{\mathrm{s}\mathrm{k}\mathrm{i}\mathrm{n}}^{208}(\mathrm{P}\mathrm{R}\mathrm{E}\mathrm{X}2)$ does $L(\mathrm{P}\mathrm{R}\mathrm{E}\mathrm{X}2)=76\sim 165$~MeV. [Conclusion] There is no overlap between $L(\mathrm{C}\mathrm{R}\mathrm{E}\mathrm{X})$ and $L(\mathrm{P}\mathrm{R}\mathrm{E}\mathrm{X}2)$. This is a big problem to be solved.
