A universal relationship between scaled size and scaled energy was explored in few-body systems$^{1,2,3}$. Ground-state self-binding energies were obtained by the diffusion Monte Carlo method. Obtained energies support generalized Tjon lines. Structural properties were extracted by pure estimators$^4$, which proved successful in evaluating theoretical predictions of distribution functions$^5$ in comparison with the experimental Coulomb explosion imaging results$^{6,7}$.

Strengthening the inter-particle interaction, the exploration was extended from halo systems, which are extremely weakly bound and prefer to be in classically forbidden regions, to classical systems.

Universal size-energy law has been found for a homogeneous system of particles when pair-potentials decay predominantly with $r^{-6}$. The law is also valid for mixed systems with homogeneous-like structure.
