Testing basic principles of particle physics does not necessarily require a high-energy accelerator. As Peter Geltenbort explains, a growing community of neutron scientists is probing similarly ...

How long do free neutrons live until they decay? This has been a hotly debated topic, because different measurement techniques lead to different results. A possible new solution has now been proposed: ...

A new study presents a method to record the temperature of materials with exceptional temporal resolution, using a Doppler broadening effect in neutron resonance absorption. Using a high-powered laser ...

Neutrons are among the basic building blocks of matter. As long as they are part of a stable atomic nucleus, they can stay there for arbitrary periods of time. However, the situation is different for ...
