Formula Sheet — Nuclei

Important formulas and equations from Nuclei for AMUEEE Physics.

Formulas — Nuclei

Nuclear Composition and Size

R = R₀ × A^(1/3)
ρ = 2.29 × 10¹⁷ kg/m³
Volume = (4/3)πR³

Mass-Energy and Binding Energy

E = mc²
ΔM = [Z·mₚ + (A-Z)·mₙ] - M
Eᵦ = ΔM × c² = ΔM × 931 MeV
BE per nucleon = Eᵦ/A

Radioactivity and Decay

N(t) = N₀e^(-λt)
T₁/₂ = 0.693/λ = ln(2)/λ
A = λN = dN/dt
N = N₀/2^n

Nuclear Reactions

Q = (m_initial - m_final) × c² = (m_initial - m_final) × 931 MeV
For fission: Q ≈ 200 MeV per U-235
For fusion: 4¹H → ⁴He + 26.7 MeV
