Dataset for the study of delocalization in the hot deformed hypernucleus $^{21}_\Lambda$Ne

The dataset contains the temperature-dependent structural and clustering properties of the hypernucleus ^{21}_{\Lambda}, calculated within the framework of deformed finite-temperature Skyrme-Hartree-Fock. The SkI4 Skyrme force is employed for nucleon-nucleon interactions, and the NSC97f force is used for hyperon-nucleon interactions. The dataset includes nuclear deformation parameters, single-Λ binding energies, entropy values, and nucleon and hyperon density distributions at multiple temperature points. At low temperatures, the hypernucleus exhibits a strongly deformed ground state with pronounced α-cluster correlations and localized density distributions. As temperature increases, nuclear deformation decreases, nucleon and hyperon densities spread over the nuclear surface, and clustering gradually diminishes, disappearing entirely at T ≈ 2.8 MeV. Due to the lower excitation threshold of hyperons, hyperon radii display a stronger temperature dependence than nucleons. This dataset provides comprehensive information for analyzing the thermal evolution of hypernuclear structure and can be used for further studies on temperature effects in hypernuclei.
