Abstract: The nuclear shell model is a benchmark for the description of the structureof atomic nuclei. The magic numbers associated with closed shells have longbeen assumed to be valid across the whole nuclear chart. Investigations inrecent years of nuclei far away from nuclear stability at facilities forradioactive ion beams have revealed that the magic numbers may change locallyin those exotic nuclei leading to the disappearance of classic shell gaps andthe appearance of new magic numbers. These changes in shell structure also haveimportant implications for the synthesis of heavy elements in stars and stellarexplosions. In this review a brief overview of the basics of the nuclear shellmodel will be given together with a summary of recent theoretical andexperimental activities investigating these changes in the nuclear shellstructure.
