Abstract

A renormalized three-body model with zero-range potential is used to estimate the mean-square radii of three-body halo nuclei and molecular systems. The halo nuclei (⁶He, ¹¹Li, ¹⁴Be and ²⁰C) are described as point-like inert cores and two neutrons. The molecular systems, with two helium atoms, are of the type ⁴He₂-X, where X=⁴He, ⁶Li, ⁷Li, or ²³Na. The estimations are compared with experimental data and realistic results.
