Nuclear Decay Processes and Energy of Nuclear Reactions
| SPONTANEOUS PROCESSES OF NUCLEAR DECAY | ||
|---|---|---|
| Alpha Decay (α) |  |  |
| Beta decay (β-) |  |  |
| Beta decay (β+)(Positron Emission) |  |  |
| ɣ-decay |  |  |
| ENERGY OF NUCLEAR REACTIONS | |
|---|---|
| Q-value | • The difference in energy equivalence (E = Δmc2) between the reactants and products. • 1u = 1.6606×10-27kg = 931.494MeV/c2 • Q > 0 Exothermic • Q < 0 Endothermic |
| KE of IncidentParticle | KEmin = (1 + m / M) |Q| m = mass of incident particle M = mass of target nucleus |
