Plot a graph showing the variation of binding energy per nucleon as a function of mass number. Which property of nuclear force explains the approximate constancy of binding energy in the range 30 < A < 170? How does one explain the release of energy in both the processes of nuclear fission and fusion from the graph?

  • The nuclear force is short-ranged represent the consistency of binding energy in the range 30 < A < 170.
  • A heavy nucleus has lower binding energy per nucleon compared to a lighter one. Suppose a nucleus width A = 240 breaks into two nuclei of A = 120, nucleons get more tightly bounded. This implies that energy would be released in fission.
  • For two ling very light nuclei (A\leq 10) joining to form a heavier nucleus. The binding energy per nucleon of heavier nucleus > binding energy per nucleon of lighter nuclei. This implies that energy is released during fission.
