Topics in Nucle

1

Atomic Masses and Nuclear Composition

  • Atomic mass unit (u) is defined as 1/12th of the mass of carbon-12 atom
  • 1 u = 1.660539 × 10⁻²⁷ kg
  • Proton mass: mp = 1.00727 u = 1.67262 × 10⁻²⁷ kg
2

Nuclear Size and Density

  • Nuclear radius R = R₀A¹/³ where R₀ = 1.2 × 10⁻¹⁵ m
  • Nuclear volume is proportional to mass number A
  • Nuclear density is constant for all nuclei ≈ 2.3 × 10¹⁷ kg/m³
3

Mass-Energy Equivalence and Binding Energy

  • Einstein's mass-energy relation: E = mc²
  • Mass defect ΔM = [Zmp + (A-Z)mn] - M
  • Binding energy Eb = ΔMc²
4

Nuclear Forces

  • Nuclear force is strongest of all fundamental forces
  • Short-range force (acts only within few femtometers)
  • Attractive at distances > 0.8 fm, repulsive at < 0.8 fm
