text: Because of the huge, nearly instantaneous neutron flux generated in the explosion, at least seventeen neutrons were successively captured by the 238 U in the thermonuclear device, producing uranium isotopes through 255 U, many of which β -decayed to higher atomic number elements, thus producing 253 Es and 255 Fm.
