Nuclear and Particle Physics Flashcards
What is conserved during Nuclear decay?
Mass and Energy Momentum Charge Baryon number Lepton number Strangeness
What is Binding Energy?
The energy required to separate an atom into its consistent parts.
What is the definition for Nuclear Activity?
The rate at which a source emits radioactive particles.
One particle emitted per second is called a Becquerel.
What is the definition for Decay Constant?
Relates activity to the number of nuclei
What quarks are a proton made of?
Up Up Down
What quarks are a neutron made of?
Up Down Down
What are the three main particle detectors?
Geiger-muller
Cloud chamber
Bubble chamber
What do particle detectors need to be able to detect?
Charge, Momentum, Direction, Multiple particles in rapid succession
What are leptons?
Fundamental particles.
What are Fermions?
Matter particles.
What are baryons?
Particles made of 3 quarks or anti quarks.
What are Mesons?
Particles made of quark and anti-quark pairs.
What are Bosons?
Force carrier particles.
What are Hadrons?
Made up of quarks and anti-quarks which experience a strong nuclear force.
What is Annihilation?
Mass is lost and transferred into energy.
Electron + Positron = Photon
