It is discovered theoretically that significant confinement resonances in an
nl photoionization of a \textit{multielectron} atom A encaged in carbon
fullerenes, A@C60​, may re-appear and be strong at photon energies far
exceeding the nl ionization threshold, as a general phenomenon. The reasons
for this phenomenon are unraveled. The Ne 2p photoionization of the
endohedral anion Ne@C605−​ in the photon energy region of about a
thousand eV above the 2p threshold is chosen as case study.Comment: 3 pages, 1 figure, Revtex
