Abstract

We investigate α-like correlations in 20Ne. A quartet of nucleons (different spin/isospin) is moving in a mean field produced by the 16O core nucleus. Improving the Thomas-Fermi model (local density approach), a shell model is considered for the core nucleus. The effective potential of the α-like quartet and the wave function for the center-of-mass (c.o.m.) motion are calculated and compared with other approaches.
