    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.
