involves the collision of two nuclei

Explanation: Nuclear fusion combines (collides and merges) two light nuclei into a heavier nucleus, releasing energy. It requires very high activation energy (temperatures/pressures) and is not yet a common energy source; it also produces far less long‑lived radioactive waste than fission (though neutron activation of materials can occur).
