Ne can be considered as a double-magic 
O core nucleus surrounded by four nucleons, the constituents of an 
-like quartet. Similar to other nuclei (
Po, 
Ti, etc.) with a quartet on top of a double-magic core nucleus, significant -like correlations are expected. Correlations in the ground state of Ne are investigated using different approaches. The quartetting wave function approach (QWFA) predicts a large -like cluster contribution near the surface of the nuclei. The Tohsaki-Horiuchi-Schuck-Röpke (THSR) approach describes -like clustering in nuclear systems. The results of the QWFA in the Thomas-Fermi and shell-model approximation are compared with THSR calculations for the container model. Results for the formation probability and the rms radii are shown.
