Formulas and Key Relations

1. Mass-Energy Relation

ΔE = (Δm)c²

Δm = ΔE / c²

E₀ = m₀c²

2. Pair Production and Pair Annihilation

hv = (-1β⁰) + (+1β⁰)

Minimum γ energy = 2 × 0.51 = 1.02 MeV

(-1β⁰) + (+1β⁰) = hv + hv

3. Mass Defect and Binding Energy

Δm = Zmp + (A−Z)mn − mN

BE = (Δm)c² = [Zmp + (A−Z)mn − mN]c²

Eb = [ZmH + (A−Z)mn − m(ZXA)]c²

Ebn = Eb / A = {[Zmp + (A−Z)mn − MN]/A} × 931.5 MeV/nucleon

Binding Energy Curve and Nuclear Stability

The binding energy per nucleon curve has almost a flat maximum from A = 50 to A = 80.

Key relations

Einstein’s relation is written as ΔE = (Δm)c².

The reaction is hv = -1β0 + +1β0.

An electron and a positron annihilate to produce two γ-photons: -1β0 + +1β0 = hv + hv.
