  1. Nuclear Physics Study 2009/08/01 Grass From CERN, Summer Student Program 2005

  2. Do you recognize me?

  3. Do you recognize me?

  5. Strong v.s. Electromagnetic

  6. Radioactivity b- decay: n  p + e- + n b+ decay: p  n + e+ + n (e.g., 14O814N7 + e+ + n) a decay: (e.g., 238U8234Th90 + 4He2 )

  7. Capture Process 3a reaction : a+a+a12C ap process : 14O+a  17F+p 18Ne 18Ne+a ... Proton capture Neutron capture

  8. The Liquid Drop Model • Their interior densities are the same • Their heats of vaporization are proportional to their masses.

  9. Magic number See the movie…

  10. Shell Model • the nuclear shell model is a model of the atomic nucleus which uses the Pauli exclusion principle to describe the structure of the nucleus in terms of energy levels.

  11. NucleosynthesisPaths X-ray Burster Super-nova

  12. The End

  13. The S-process acting in the range from Ag to Sb. http://en.wikipedia.org/wiki/S-process
