why are nuetrons easier to use for nuclear bombardment than alpha or beta particles

Think about it. Alpha particles have a positive change which makes it difficult for them to get close to a positively charged nucleus. Right? And the beta particles (electrons which are negatively charged) must navigate through a sea of electrons of the same charge (the outside shells of electrons) before getting to the nucleus.

I didn't say it but the neutrons are neutral so they don't have the kinds of "electrical" problems that positively charged and negatively charged particles have.
