Sažetak
Universal relationship of scaled size and scaled energy is explored in few-body systems. Ground- state self-binding energy is obtained by the diffusion Monte Carlo method, while structural properties are extracted by pure estimators. A similar approach proved successful in comparison of theoretically predicted distribution functions in helium clusters with the experimental results, which were drawn from Coulomb explosion imaging of diffracted helium clusters. A detailed study was performed in the halo region, where systems are extremely weakly bound and prefer more to be in classically forbidden regions. Strengthening the inter-particle interaction we extend the exploration all the way to classical systems. Universal size-energy law has been found for a homogeneous system of particles, whose pair- potentials decay predominantly with $r^{;-6};$. The law is also valid for mixed systems with homogeneous-like structure.
