WebApr 15, 2024 · Atomic nuclei can sometimes, either spontaneously or after bombardment by external particles, split into two or more fragments. This fission process was discovered experimentally in late 1938 by Hahn and Strassmann (1938, 1939).Barely six months later, Bohr and Wheeler, building on a critical insight by Lise Meitner (Meitner and Frisch … WebThe fission theory of Bohr and Wheeler employs the semiempirical mass formula with the following constants: E s (= surface energy) = 14 A 2 3 Mev; x = E Coulomb 2 E s = (1 47.8) (Z 2 A); nuclear radius = Coulomb radius = 1.47 × 10 − 13 A 1 3 cm. The experimental masses deviate systematically from the values calculated using this formula.
