How does Aston's work relate to modern nuclear energy?
My measurements of packing fractions—the small mass differences between isotopes and the sum of their nucleons—directly relate to nuclear energy. The packing fraction curve I constructed shows that iron has the most stable nucleus, while lighter and heavier elements can release energy through fusion or fission. For example, the mass defect in uranium isotopes indicates the energy released in nuclear fission. The mass spectrograph revealed these precise mass differences, which are now used to calculate binding energies. Modern nuclear reactors and weapons rely on this principle. My work also enabled the separation of uranium-235 from uranium-238, essential for both power generation and atomic bombs. Thus, the experimental data from my apparatus laid the groundwork for understanding nuclear reactions and their practical applications.
