Nuetron Neutrality: How Does it Have an Anti-Particle?

[cragar]

if the nuetron is nuetral in charge then how does it have an anti-particle?

A neutron (note spelling) is a composite particle. It is made of an up-quark (charge +2/3 e) and two down-quarks (each with charge -1/3 e). An antineutron is made of an anti-up-quark and two anti-down-quarks.

oh i see , how do they accelerate neutrons!

 

[jtbell]

As far as I know, we don't accelerate neutrons. We produce them with the desired energy, by some suitable reaction. Once we have them, we can block them with shielding, but we can't accelerate or "steer" them.

what about the Neutron magnetic moment?

Do you suggest to use the magnetic moment to accelerate neutrons ? Usually when we talk about particle accelerators, we're mostly interested in this part of the acceleration which is parallel to the momentum.

im just asking is it possible

As far as I know, yes it is possible, using gravity, so it's not quite effective.

But if the goal is to produce a neutron beam, there are spallation sources as well.

i see thanks for the info.
