20Ne can be considered as a double-magic 16O core nucleus surrounded by four nucleons, the constituents of an α-like quartet. Similar to other nuclei (212Po, 104Ti, etc.) with a quartet on top of a double-magic core nucleus, significant α-like correlations are expected. The quartetting wave function (QWF) approach predicts a large α-like cluster contribution near the surface of the nuclei. The Tohsaki-Horiuchi-Schuck-Röpke (THSR) approach describes α-like clustering in nuclear systems. The results of the QWF approach in the Thomas-Fermi and shell-model approximation are compared with THSR calculations for the container model.
