HONR228Q Notes section i:

  • Basic Nuclear Structure

    1. Variety of forces in nature

      1. Gravitational force
        1. Weakest
        2. Longest range
        3. Range virtually infinite
        4. Responsible for the universe
      2. Electromagnetic forces
        1. Intermediate strength
        2. Inermediate range
        3. Range of size of atom ~10-10 meter
        4. Responsible for the configuration of the atom
      3. Nuclear force
        1. Strongest
        2. Shortest range
        3. Responsible for the configuration of the nucleus
        4. Range of size of nucleus ~10-15 meter

    2. Symbols and Terms

      1. Symbols
        1. Z = number of protons
        2. N = number of neutrons
        3. A = Z + N = atomic weight
      2. Terms
        1. Nuclide = any specific nucleus (Z,N)
        2. Isotope = same Z but different N (the same chemical element)
        3. Isotone = same N but different Z
        4. Isobar = same A

    3. The Chart of the Nuclides

      1. KAERI Web-based chart of the nuclides(BNL server)
      2. KAERI Web-based chart of the nuclides(Korean server)
        1. Note: web site by Korean Atomic Energy Research Institute
        2. Detailed chart of the nuclides for study using the web
        3. Links in table provide detailed information
      3. LUNDS Universitet Nuclear Data Dissemination Home Page: lots of information about isotopes, nuclear decay half-lives, etc.
      4. DEMO P4-21: NUCLIDES CHART
        1. Includes all known nuclides
        2. Ordered by proton number Z and neutron number N
        3. Hand out for individual use during class
      5. Some features
        1. Identifies isotopes by Z and N
        2. Gives relative abundance for each isotope
        3. Gives origin, if radioactive
        4. Gives radioactive half life, if unstable
        5. Gives radioactive decay modes and energies of emitted particles
