DESCRIPTION

It's on Nuclear Physics, but without my lecturing along with it, it might not make much sense.

Brief Overview:Four Fundamental Forces: Gravitation Electromagnetism Strong NuclearWeak NuclearTuesday, May 28, 13 5. Tuesday, May 28, 13 6. Attraction by force proportional to masses andinversely proportional to the square of the distanceTuesday, May 28, 13 7. Tuesday, May 28, 13 8. Electric charges attract or repel oneanother with a force inversely proportionalto the square of the distance between themTuesday, May 28, 13 9. Tuesday, May 28, 13 10. ~Violation of SymmetryDecay through weak interaction~Electroweak TheoryThe rst type is called the "charged current interaction" because it is mediated byparticles that carry an electric charge (the W+ or W bosons), and is responsiblefor the beta decay phenomenon. The second type is called the "neutral currentinteraction" because it is mediated by a neutral particle, the Z boson.Tuesday, May 28, 13 11. Tuesday, May 28, 13 12. Tuesday, May 28, 13 13. Tuesday, May 28, 13 14. Nuclear FusionTuesday, May 28, 13 15. Nuclear FusionFusion of deuterium with tritium creating helium-4, freeing a neutron, andreleasing 17.59 MeV of energy, as an appropriate amount of mass changingforms to appear as the kinetic energy of the products, in agreement withkinetic E = mc2, where m is the change in rest mass of particles.1u0 + 235U92 --> 236U*92 --> FF1 + FF2 + (2-5u)Tuesday, May 28, 13 16. Half-life decayTuesday, May 28, 13 17. Half-life decayThe amount of time it takesfor the substance to havedecayed halfway (or to havelost half of its... substance).That simple.Tuesday, May 28, 13 18. Alpha Decay/EmissionTuesday, May 28, 13 19. Alpha Decay/EmissionTuesday, May 28, 13 20. Beta Decay/EmissionTuesday, May 28, 13 21. Beta Decay/EmissionElectron or positron (anti-electron) emission... toobtain the optimal ratio or protons to neutrons.Electron emission is Beta Minus () and positronemission is Beta Plus (+).anti-neutrinoelectron neutrinoTuesday, May 28, 13 22. Gamma Decay/EmissionTuesday, May 28, 13 23. Gamma Decay/EmissionThe mechanism is that when a nucleus emits an or particle, the daughter nucleus is usually left in an excitedstate. It can then move to a lower energy state by emitting a gamma ray, in much the same way that an atomic electroncan jump to a lower energy state by emitting a photon. Emission of a gamma ray from an excited nuclear state typicallyrequires only 1012 seconds, and is thus nearly instantaneous. Gamma decay from excited states may also follow nuclearreactions such as neutron capture, nuclear ssion, or nuclear fusion.Tuesday, May 28, 13 24. "Alpha Emission." Wikipedia.
