Abstract: Strong odd-even staggering (OES) of the yields of fragments, produced by fragmenting Kr⁷⁸ projectiles, has been measured by employing the combination of an in-flight fragment separator and a storage ring. It is shown that the OES of fragment yields of T_z=−1/2 and T_z=1/2 mirror nuclei critically depends on both pairing and shell structure, especially at the closed shells Z=20 and 28. A comparison of the relative OES of yields and of particle-emission threshold energies reveals unambiguously that the origin of the OES of fragment yields is mainly determined by the OES of the particle-emission threshold energies, which contain both pairing and shell effects.
