6. Work…continued * Proposed shell nucleur model * Worked with Uranium Club * Uranium club worked to separate uranium isotopes * Double centrifuge based on a rocking process

7. Books * Elementary Theory of Nuclear Shell Structure * Nobel Lectures * Paul Harteck * Konrad Beyerle

8. Shell Atomic Model * Arrangement of electrons in an atom * Developed in 1949 * Filled shell-greater stability

9. Shell Atomic Model * Electrons are occupying diffuse shells * Closest atom closest to the nucleus * Others extend outward from that one

10. Contribution * Proposed the shell theory of nuclear structure * Structure of nucleons, protons and neutrons * Shared Nobel Prize in physics

11. Contribution * Suggested nucleons spun on their axis in orbit * Number of nucleons/shell made nucleus more stable * Certain patterns in the nucleons around the nucleus
