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.
