Topics in Mass- Energy Equivalence: Nuclear Binding Energy

1

Mass-Energy Relation

  • Mass and energy are interconvertible.
  • If a substance loses mass, an equivalent amount of energy is produced.
  • If energy is supplied to matter, its mass increases by a very small amount.
2

Pair Production and Pair Annihilation

  • Pair production converts energy into mass.
  • Pair annihilation converts mass into energy.
  • Pair production occurs when an energetic gamma photon falls on a heavy substance and produces an electron and a positron.
3

Mass Defect and Nuclear Binding Energy

  • The rest mass of a stable nucleus is less than the sum of the masses of its free protons and neutrons.
  • The difference is called mass defect.
  • Mass defect appears as binding energy.
4

Binding Energy Curve and Nuclear Stability

  • Nuclear binding energies range from 2.23 MeV for heavy hydrogen to about 1800 MeV for uranium.
  • Higher binding energy per nucleon means greater stability.
  • The binding energy per nucleon curve has almost a flat maximum from A = 50 to A = 80.

Key Concepts
