R. Guardiola et al., 2-BODY AND HYPERRADIAL CORRELATIONS IN THE DESCRIPTION OF MANY-BODY SYSTEMS, Physics letters. Section B, 383(3), 1996, pp. 243-246
By studying a simple bosonic system, we analyze the importance of hype
rradial correlations and quantify the performances of the Integro-Diff
erential Equation Approach to the Hyperspherical Harmonics Method and
the Second-order Translationally Invariant Coupled Cluster Method.
