Neon dimers in momentum and configuration spaces.

Abstract

This work investigates the rovibrational energy levels of the Neon dimer using the Lippmann-Schwinger equation in both configuration and momentum spaces. By analyzing the wave functions and interatomic separations, we provide a detailed characterization of the binding energies and spatial properties of the Neon dimer. Results indicate strong agreement between configuration and momentum space calculations, with deviations remaining below [Formula: see text]. Momentum space solutions exhibit enhanced precision for weakly bound states due to their localization at lower momenta. Comparisons with existing theoretical data validate the robustness of the approach, offering a reliable framework for studying other rare gas dimers and extending to larger clusters to deepen the understanding of intermolecular interactions in quantum systems.
