How do you strip a neutron from a particle? Thanks

Well, a neutron is considered a particle. A proton, deuteron, triton, or He nucleus (alpha particle) are considered particles.

What particle did on have in mind?

Neutrons can be removed from nuclei by interaction with gamma ray of appropriate energy. If a gamma ray of energy > ~2.22 MeV interacts with deuteron, the neutron and proton may part in a reaction known a photodissociation. Otherwise, if a sufficiently energetic gamma photon cause a neutron to be ejected from a nucleus, the reaction is termed 'photo-emission'.

Some fusion reactions also release neutrons, e.g., d+t => α + n, or d+d => He-3 + n (~50%).

Some nuclear reactions may result in the release of neutrons, e.g., a highly energetic proton or neutron can knock a neutron out of an atom. The reaction is term spallation.

A common portable laboratory source of neutrons is a mixture of an alpha emitter and beryllium: a fine powder mixture of plutonium and beryllium (PuBe) or americium and beryllium (AmBe). The absolute yield is in the range of 50 neutrons per million alphas. See http://prola.aps.org/abstract/PR/v98/i3/p740_1
