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 ...

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 ...

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 ...

New research explains how gold and other heavy elements are created in space when stars collapse or collide, solving a long-standing mystery.

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 ...

The far future of the cosmos may be less endless than it once appeared. New calculations place the decay of the universe’s ...

All the matter we know of in our Universe is made of both fundamental and composite particles. However, only a few of the fundamental particles are observed to be stable and not to decay into other ...

A research team at the Facility for Rare Isotope Beams (FRIB) is the first ever to observe a beta-delayed neutron emission from fluorine-25, a rare, unstable nuclide. Using the FRIB Decay Station ...

A neutron decays into a proton, an electron, and an antineutrino. In the QCD lattice approach, a discrete space is used for the calculation. The different colours on the lattice represent the gluons ...
