    "abstract": "We investigate different correlation mechanisms for two-electron systems and\ncompare their respective effects on various electron distributions. The\nsimplicity of the wave functions used allows for the derivation of closed-form\nanalytical expressions for all electron distributions. Among other features, it\nis shown that angular and radial correlation mechanisms have opposite effects\non Compton profiles at small momenta.",
