The third also gives two beta electrons. In total, every 238U decay eventually produces 5 beta electrons, randomly distributed with a complex function of the listed lifetimes. The radioactive isotope 238U decays in a series of nuclear reactions that includes another uranium isotope, 234U, and three lead isotopes, 214Pb, 210Pb, and 206Pb.

The photofission of 232Th, 234U and 238U at excitation energies in the barrier region has been studied. The goal has been to extract information on the mass, total kinetic energy (TKE) and angular distributions of the fission fragments. The experiments were performed using bremsstrahlung, produced by an electron beam in a copper radiator at the injector of the Superconducting Darmstadt linear

• Describe the properties of decay products of uranium.Describe the properties of decay products of uranium. The number gives number of nucleons in a nucleus. uranium-235 has 235 nucleons and uranium-238 has 238 nucleons. The number of protons (which also give a charge to a nucleus) are same in the two
