A new "bathtub" experiment has allowed physicists to measure the lifetime of a free neutron far more precisely than ever before. The breakthrough could help probe the fringes of the Standard Model of ...
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 ...
A free neutron outside a nucleus is not stable. It undergoes beta decay at a probability. Over time, the number of free neutrons decreases exponentially at a time constant, which is called the neutron ...
The neutron-rich oxygen isotopes oxygen-27 and oxygen-28 exist as very short-lived resonances, report scientists based on the first observation of their decay into oxygen-24 and three and four ...

Infamous 'neutron lifetime puzzle' may finally have a solution — but it involves invisible atoms
A mysterious second flavor of hydrogen atoms — one that doesn't interact with light — may exist, a new theoretical study proposes, and it could account for much of the universe's missing matter while ...
GAITHERSBURG, MD -- Researchers from the Commerce Department's National Institute of Standards and Technology (NIST) and four universities have made the first experimental observation of rare ...
(Inside Science) — Scientists have been trying to measure the lifetime of a neutron outside an atomic nucleus for decades, and for the last 15 years, two types of laboratory experiments have provided ...
An international team of researchers recently measured the lifetime of a neutron outside of an atomic nucleus with extraordinary precision. By their measurements, the neutron survived for 14.629 ...

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: ...
