Physics AS- Particles and radiation spec

Seite 1

1a- Structure of atom

1b- charge and mass of proton, neutron and electron (units)

1c- What proton number A and Z represent also nuclide notation

1d- Specific charge (units Ckg^-1)

1e- Isotopes and their data use

1f-Role of strong nuclear force and effect for following ranges : o.5fm, between 0.5fm amd 3fm, more than 3fm

1g- Alpha and Beta decay

1h- Neutrino hypothesis

1i- Photons are wave packets of em radiation

1j- E=hf

1k- Particles and antiparticles equal mass, rest energy and charge but opposite

1l- Antiparticles of electron, proton, neutron and neutrino

1m- Pair production and annihilation, calculate energies involved

1n- Hadrons: Baryons and mesons (anti as well)

1o- Proton only stable baryon all others eventually decay to a proton

1p- Exchange particle for strong force = pion

1q- Kaon decays to pion, and muon decays into electron

1r- Baryon and lepton number must be conserved also different lepton numbers for electrons and muons

1s- Strange particles created through strong interaction, and decay through weak interaction

1t- Strange particles always created in pairs (quantum number)

1u-Energy, charge, momentum, baryon, and lepton number must be conserved in all reactions

1v- Know up, down and strange quarks (anti as well) ,properties and compositions

1w- Exchange particles used to explain the interaction between particles

1x-Four fundamental interactions: gravity, electromagnetic, weak nuclear and strong nuclear

1y- weak interaction can change a quark's character (beta decay, electron capture and electron-proton collisions know these Feynman diagrams)

1z-The exchange particles for electromagnetic force and weak interaction, Also that large teams of scientists and engineers working together.
