Binding energy is the mass-defect energy of a nucleus. A heavy nucleus can split only when the total mass of the products is smaller, and light nuclei can fuse when the final mass is smaller. Use the following neutral-atom masses (u): ¹₁H 1.007825, ²₁H 2.014102, ³₁H 3.016050, ⁴₂He 4.002603, ⁶₃Li 6.015123, ⁷₃Li 7.016004, ⁷⁰₃₀Zn 69.925325, ⁸²₃₄Se 81.916709, ¹⁵²₆₄Gd 151.919803, ²⁰⁶₈₂Pb 205.974455, ²⁰⁹₈₃Bi 208.980388 and ²¹⁰₈₄Po 209.982876. Take 1u=932 MeV c⁻².
