Abstract
Short-range correlations in bosonic Helium clusters, composed of He atoms, are studied utilizing the generalized contact formalism. The emergence of universal -body short range correlations is formulated and demonstrated numerically via Monte Carlo simulations. The values of the -particle contacts are evaluated for . In the thermodynamic limit, the two-body contact is extracted from available experimental measurements of the static structure factor of liquid He at high momenta, and found in a good agreement with the value extracted from our calculations.
