Abstract
Abstract$$^{20}$$
20
Ne can be considered as a double-magic $$^{16}$$
16
O core nucleus surrounded by four nucleons, the constituents of an $$\alpha $$
α
-like quartet. Similar to other nuclei ($$^{212}$$
212
Po, $$^{104}$$
104
Ti, etc.) with a quartet on top of a double-magic core nucleus, significant $$\alpha $$
α
-like correlations are expected. Correlations in the ground state of $$^{20}$$
20
Ne are investigated using different approaches. The quartetting wave function approach (QWFA) predicts a large $$\alpha $$
α
-like cluster contribution near the surface of the nuclei. The Tohsaki-Horiuchi-Schuck-Röpke (THSR) approach describes $$\alpha $$
α
-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 $$\alpha $$
α
formation probability and the rms radii are shown.
