We study isolated core excitation of ultracold ytterbium Rydberg atoms of high orbital angular momentum quantum number \ensuremathℓ. Measurements were performed on the 6s1/240\ensuremathℓ\ensuremath→6p1/240\ensuremathℓ transition with \ensuremathℓ=5--9. The extracted energy shifts and autoionization rates are in good agreement with a model based on independent electrons, taking interactions into account in a perturbative approach. We reveal a slow decrease in the autoionization rates with \ensuremathℓ, explained by the strong coupling of the 6p1/2n\ensuremathℓ autoionizing state with the 5d3/2\ensuremathε\ensuremathℓ^\ensuremath' continua compared to previously studied divalent atoms.
