Abstract: Periodic spatial structures formed by cooled beams of free ions of the same sign in traps of one or another type are considered. These structures can be treated as quasi-crystals. Coherent nuclear radiative processes proceeding in the beams depend on a regular arrangement of nuclei in the structure of such crystallised ion beams. These processes include the Dicke superradiance, directional emission of gamma quanta, the establishment of a distributed feedback, and the appearance of the hidden inversion of nuclear states. Conditions required for the emergence of these effects are quantitatively estimated.
