The maximum distance between two deuterium nuclei required to overcome the Coulomb barrier and achieve fusion is approximately 1 femtometer (fm), which is the effective range of the strong nuclear force. There is no sharply defined distance for this interaction, as the fusion process involves probabilistic quantum mechanics rather than a fixed threshold. Understanding this range is crucial for nuclear fusion research and applications.
PREREQUISITESPhysicists, nuclear engineers, and researchers involved in nuclear fusion studies or related fields will benefit from this discussion.
