Shape-Shifting Experiment Challenges Interpretation of How Cadmium Nuclei Move
Atomic nuclei take a range of shapes, from spherical to football-like deformed. Spherical nuclei are often described by the motion of a small fraction of the protons and neutrons, while deformed nuclei tend to rotate as a collective whole. A third kind of motion, nuclear vibration, has been proposed since the 1950s. However, a new investigation of cadmium-106 nuclei found that these nuclei rotate, not vibrate, counter to scientists’ expectations.
