When it comes to particle physics, however, much of the action takes place in giant accelerators smashing particles together ...

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 ...

Perspective's promising PRRT trial results and solid financial position make CATX stock an attractive long-term investment ...

An unstable nucleus can emit a ‘package’ of two protons and two neutrons, called an alpha particle, to become more stable. Alpha radiation is made up of a stream of alpha particles emitted ...
