What attracts neutrons?

Could you elaborate on the forces that draw neutrons towards specific entities? What properties or conditions lead to the attraction of neutrons, and how does this phenomenon play a role in nuclear physics? Are there any specific examples where the attraction of neutrons has significant implications for our understanding of matter or energy transformations? I'm particularly interested in knowing about the interaction between neutrons and other subatomic particles, as well as the role of neutron attraction in nuclear reactions and the stability of atomic nuclei.
