    "abstract": "We consider a general central-field system in D dimensions and show that the\ndivision of the kinetic energy into radial and angular parts proceeds\ndifferently in the wavefunction picture and the Weyl-Wigner phase-space\npicture. Thus, the radial and angular kinetic energies are different quantities\nin the two pictures, containing different physical information, but the\nrelation between them is well defined. We discuss this relation and illustrate\nits nature by examples referring to a free particle and to a ground-state\nhydrogen atom.",
