ALPHA will extend the search for a hypothetical dark matter candidate—a very low-mass particle called the axion ... available systems, which are helium dilution fridges that are able to ...

It produces an alpha particle (or Helium-4 nucleus) and a neutron, and releases 17.6 megaelectron volt (MeV) of energy in the form of kinetic energy of the products (3.5 MeV to alpha particle and 14.1 ...

For the first time, scientists have directly measured a weak r-process reaction using a radioactive ion beam, shedding light ...

Physicists have measured a nuclear reaction that can occur in neutron star collisions, providing direct experimental data for a process that had previously only been theorised. The study, led by the ...

Figure caption, An alpha particle is also a Helium-4 nucleus. An alpha particle is made up of two protons and two neutrons which is the same as a helium nucleus. For this reason, an alpha particle ...

An alpha particle consists of two protons and two neutrons and is often described as a helium nucleus. It is not the same as a helium atom as it does not contain any electrons but it is written ...

Physicists have measured a nuclear reaction that can occur in neutron star collisions, providing direct experimental data for a process that had previously only been theorised. The study provides new ...
