Webnuclear fusion, process by which nuclear reactions between light elements form heavier elements (up to iron). In cases where the interacting nuclei belong to elements with low atomic numbers (e.g., hydrogen [atomic number 1] or its isotopes deuterium and tritium), substantial amounts of energy are released. The vast energy potential of nuclear fusion … WebMar 10, 2024 · But this process can only produce the first 26 elements up to iron. Another process, known as rapid neutron capture, is thought to produce nuclei that are heavier than iron. As its name suggests,...
