What are the properties of a neutron?

1) Neutron is an uncharged particle and hence it is not deflected by the electric and magnetic fields.
2) It has very high penetrating power and has very low ionization power.
3) Inside the nucleus neutrons are stable, but outside the nucleus it is unstable and it decays into a proton, electron and an antineutrino in 1000 seconds.

4) If fast neutron pass through substances like heavy water, paraffin wax, graphite etc. They are slowed down.
5) Neutrons are diffracted by crystals.
