摘要：

Highly excited sates of neutral CO lying in the 20-40-eV excitation energy range, i.e., up to the double-ionization threshold energy, are studied by means of synchrotron radiation. They are observed as resonances in the ion-yield curves, which measure the O- and C- negative-fragment-ion intensity as a function of the photon excitation energy. Narrow resonances are assigned to doubly excited Rydberg-state series converging to CO+ satellite states.
