| Abstract: | An analogy is presented between periodic persistent currents in mesoscopic rings and staggerings of gamma energy transitions
from some nuclear high-spin states. Various sources of damping of the expected periodic structures in both physical systems
are compared. This discussion provides, in the nuclear case, a tentative explanation of the scarcity of such staggerings,
their appearance near 150Gd and the existence of a spin-window for their observation.
