Quasiatom

Quasiatoms are collections of atomic or sub-atomic particles that when undergoing a collision that briefly appear to have the same characteristics as a (larger) atom. This can occur when the nuclei of the two set of particles colliding become much closer to each other than they are to their constituent electrons. The combined nuclei then exhibit the same 1/r force as a single nucleus.
