How is neutron formed

WebThere are two main methods of producing neutrons for materials research. One is by splitting uranium atoms in a nuclear fission reactor. The other, called spallation, involves … WebA neutron is a sub-atomic particle with no net electrostatic charge, with a very similar mass to a proton. Neutrons are thought to comprise of one up quark of charge +2/3 and two down quarks of charge -1/3 each, resulting in a net charge of zero. Neutrons are present in almost all atomic nuclei except for Hydrogen.
