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 ...

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 ...

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 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 ...

A worldwide collaboration of scientists has announced the most precise measurement ever taken of a neutron's lifetime. How? By giving neutrons a nice long soak in an ultracold "neutron bathtub." Share ...

The most luminous kilonova candidate to date (short gamma-ray burst 200522A) was detected using the Hubble Space Telescope, ...

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 ...

The study of physical systems under extreme conditions offers valuable insights into their organization and structure. In nuclear physics, neutron-rich isotopes, especially the light ones with neutron ...
