Revolutionary Measurement Sets New Record for Free Neutron Lifetime
A Los Alamos-led team has achieved a new world-record precision in measuring the free neutron lifetime at 877.83 seconds, using an improved magneto-gravitational trap called UCNTau, which incorporates advanced techniques like an innovative elevator system to load neutrons. The results help address fundamental questions in physics and pave the way for next-generation experiments aiming for even greater accuracy.
