Unlocking Potential of 3D Printed Rocket Parts with Neutrons

Although the neutron is a senior citizen of sorts, whose existence was predicted in 1920 and confirmed in 1932, it’s still not fully understood. Both Snell’s and Robson’s time ranges for neutron half-life span the currently estimated value, somewhere around 10.2 minutes, but the hunt continues. ORNL—through the Spallation Neutron Source's Fundamental Physics Beam Line—is one of more than a dozen institutions around the world working to pin down this elusive number.

Illustration shows the one dimensional Yb ion chain in the quantum magnet Yb2Pt2Pb. The Yb orbitals are depicted as the iso-surfaces, and the green arrows indicate the antiferromagnetically aligned Yb magnetic moments. The particular overlap of the orbitals allows the Yb moments to hop between the nearest and next nearest neighbors along the chain direction, resulting in the two and four spinon excitations.
