Bound 4d inner-shell excited states have been observed as 4d{sup 10}5s{sup 2}5p{sup 5}{yields}4d{sup 9}5s{sup 2}5p{sup 6} {sup 2}D{sub 5/2,3/2} Feshbach resonances in the photodetachment spectrum of Te{sup -} utilizing the merged-beam technique at the storage ring ASTRID. The strong binding of these core-excited levels, 2.95 and 1.47 eV respectively, is attributed to the extra stability of the full 5p shell. The role of the present data as a prototype spectrum for negative ions having an outer shell with a single vacancy in the initial state is discussed.
