Ab Initio Methods Help Scientists Make Sense of Complex Particle Collisions
Research finds ab initio effective field theories are useful for calculating how nucleons scatter from collisions of atomic nuclei.

Studying the shape can help explain the physics of fast-rotating nuclei.](/-/media/np/images/highlights/2024/Louisiana-S-U-image.png?h=296&w=448&la=en&hash=0A314C2CBF42DADDC81A0A5E860691E0D3D30815FF52306C3072E898760E9BCD)
Resolved: A Long-Debated Anomaly in How Nuclei Spin
Scientists resolve the hypothesized anomalous increase in moment of inertia of fast rotating nuclei with models of neon-20 and chromium-48 nuclei.
