What are neutrons?

Some articles on neutrons, neutron:

Atomic Nucleus - Forces
... binds quarks together to form protons and neutrons ... This force is much weaker between neutrons and protons because it is mostly neutralized within them, in the same way that electromagnetic forces between neutral atoms (such as van der Waals ... beta, and gamma decay) nucleus is lead-208 which contains a total of 208 nucleons (126 neutrons and 82 protons) ...
Scattering Amplitude - Neutrons
... The nuclear neutron scattering process involves the coherent neutron scattering length, often described by ...
Atomic Nucleus - Protons and Neutrons
... Protons and neutrons are fermions, with different values of the strong isospin quantum number, so two protons and two neutrons can share the same space wave function since they are not ... Two fermions, such as two protons, or two neutrons, or a proton + neutron (the deuteron) can exhibit bosonic behavior when they become loosely bound in pairs ... The neutron has a positively charged core of radius ≈ 0.3 fm surrounded by a compensating negative charge of radius between 0.3 fm and 2 fm ...
Clean And Environmentally Safe Advanced Reactor
... Claudio Filippone, it can be used to fine tune neutron fluxes to ensure that neutrons are moving with an optimal neutron energy profile to split 238 92U nuclei ... via nuclear reactions also decay to produce additional delayed neutrons. 235U fuel rods moderated by liquid water coolant ultimately creates a Maxwellian thermal neutron flux profile, the neutron energy profile from delayed neutrons varies widely ...
Clementine (nuclear Reactor) - Reactor Control
... first reactor to demonstrate reaction control via control of delayed neutrons, this was more of a function of being one of the very early reactors rather than a special design feature. 238U is a good neutron reflector so the position of the blanket controlled the number of neutrons available to the reaction ... When the blanket was raised more neutrons were reflected back into the core causing a greater number of fissions and consequently greater power output ...
