With the completion of the heavy ion linear accelerator (HILAC) at Berkeley Lab in 1957, a double-recoil method was put to work to identify nobelium (102).
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.
