摘　　要：How does the strong force shape the structure of atomic nuclei- The STAR collaboration at the BNL Relativistic Heavy Ion Collider(RHIC) demonstrate that ultra-relativistic collision experiments give key insights into this fundamental question. From dedicated measurements in ^(238)U+^(238)U collisions at 100 GeV/nucleon energy, the STAR collaboration determine the deformed shape of the ^(238)U nucleus, showing in particular that the experimental observables probe the elusive ground-state triaxiality of this isotope. These results pave the way to systematic characterizations of ground-state nuclear properties at high-energy colliders.
