Basic Answer:
The terms "electron-phonon interaction" and "phonon-electron interaction" mean the same thing and one almost always hears the former and not the latter. In a nutshell the term refers to the fact that the usual idea of separating the quantum system of electrons and the quantum system of vibrations (phonons) is an approximation that does not answer questions about the exchange of energy between the two systems. The next most sophisticated treatment involves including a term in the Hamiltonian that approximates the mechanism for that energy exchange. That term is called the electron-phonon interaction term.
Addendum on Electron-Phonon Interaction:
If the question were posed asking to explain the electron-phonon interaction, this answer would have to discuss the process of calculating electronic energies for fixed nuclei and then solving the problem where the nuclei are allowed to move within the adiabatic approximation. That leads to the two quantum systems mentioned above and thus to the need for an improvement which treats electrons and nuclei both being treated at the same time in a quantum mechanical fashion. One proceeds with an electronic Hamiltonian and a nuclear coordinate Hamiltonian and adds a third term called the electron-phonon interaction which is meant to be a good approximation to the full quantum system and is amenable to reasonable approximation methods.

What is the primary difference between interaction webs and food webs?
Food webs specifically show the flow of energy and nutrients through an ecosystem via feeding relationships, while interaction webs include other types of relationships such as competition, predation, and mutualism. Interaction webs provide a more comprehensive view of the complex interactions within an ecosystem beyond just who eats whom.
What is the Pion-Nucleon Interaction?
The pion-nucleon interaction refers to the strong force interaction between a pion (a type of meson) and a nucleon (proton or neutron). Pions are exchanged between nucleons to transmit the strong nuclear force, which binds protons and neutrons together in atomic nuclei. This interaction is crucial for understanding nuclear structure and properties.
What are some ecological example of a refuge?
(1) In a well-mixed population, the predator quickly finds prey, the prey disappear, and the predator soon follows. (2) By increasing the space between population subunits, the interaction between the predator and prey is prolonged. (3) By slowing the movement of the predator, the interaction between the predator and prey is prolonged. (4) By adding habitat patches that don't support prey, the interaction between the predator and prey is prolonged. (5) By adding barriers to predator dispersal, the interaction between predator and prey is prolonged.

Is of2 a dipole-dipole interaction?
No, OF2 is not a dipole-dipole interaction. It exhibits a polar covalent bond due to the difference in electronegativity between oxygen and fluorine. Dipole-dipole interactions occur between different molecules that have permanent dipoles.

What is the difference between interaction and interrelation in human relations?
Interaction refers to the act of engaging or communicating with others, while interrelation involves the mutual connections or influences between different entities. In human relations, interaction focuses on the direct exchanges between individuals, whereas interrelation emphasizes the broader network of relationships and dependencies that exist among people.
