Topics in Nuclei
1
Atomic Masses and Composition of Nucleus
- The nucleus contains protons and neutrons (collectively called nucleons)
- Atomic number (Z) = Number of protons
- Mass number (A) = Number of protons + Number of neutrons
2
Size of the Nucleus
- Nuclear radius R = R₀A^(1/3) where R₀ = 1.2 × 10⁻¹⁵ m
- Nuclear volume is proportional to mass number A
- Nuclear density is constant for all nuclei ≈ 2.29 × 10¹⁷ kg/m³
3
Mass-Energy and Nuclear Binding Energy
- Mass defect (Δm) = [Z·mₚ + (A-Z)·mₙ] - M
- Binding energy Eᵦ = Δm·c² (energy equivalent of mass defect)
- Binding energy per nucleon = Eᵦ/A
4
Nuclear Force
- Nuclear force is strongest force in nature within its range
- Acts only within ~1 fm range (short-range force)
- Charge independent - same between p-p, p-n, and n-n pairs
