Rényi information of atoms

Abstract Position and momentum space Renyi information of order α has been studied within a Hartree–Fock framework for 103 neutral atoms, 54 singly charged cations and 43 anions in their ground state. The values of α ⩽ 1 ( α ⩾ 1 ) stress the shell structure for position-space (momentum-space) Renyi information. The relationship between the complexity and Renyi information is also studied.
