text: Each term is proportional to the matrix element ⟨ k ( 0 ) | V | n ( 0 ) ⟩ {\displaystyle \langle k^{(0)}|V|n^{(0)}\rangle } , which is a measure of how much the perturbation mixes eigenstate n with eigenstate k; it is also inversely proportional to the energy difference between eigenstates k and n, which means that the perturbation deforms the eigenstate to a greater extent if there are more eigenstates at nearby energies.
