The radial part depends on the analytical form of the potential, but the angular part does not. In this article, we first calculate the angular entropy of any central potential by means of two analytical procedures. Then, we explicitly find the dominant term of the radial entropy for the highly energetic (i.e., Rydberg) stationary states of the oscillatorlike systems. The angular and radial contributions to these entropic measures are analytically expressed in terms of the quantum numbers which characterize the corresponding quantum states and, for the radial part, the oscillator strength. In the latter case, we use some recent powerful results of the information theory of the Laguerre polynomials and spherical harmonics which control the oscillator-like wavefunctions.engEntropic measures of Rydberg oscillator statesInformation theory of the harmonic oscillatorRenyi and Tsallis entropies of the harmonic oscillatorShannon entropy of the harmonic oscillatorAngular entropies of any central potentialinfo:eu-repo/semantics/article10.1002/qua.25315info:eu-repo/semantics/openAccess
