The most neutron-rich matter that can be made on Earth--the nucleus of the helium-8 atom--has been created, trapped and characterized by researchers. This new measurement gives rise to several ...

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 unexpected deformation has been discovered in the helium-8 nucleus by an international team led by Matthias Holl and Rituparna Kanungo, both at Saint Mary’s University in Canada. The researchers ...

When theoretical physicists like myself say that we’re studying why the universe exists, we sound like philosophers. But new data collected by researchers using Japan’s Subaru telescope has revealed ...

A research team has achieved a significant breakthrough in determining fundamental properties of atomic nuclei. The team conducted laser spectroscopy experiments on muonic helium-3. Muonic helium-3 is ...
