Reflections on the Shell Model
- Robert Janssens
The magic numbers that inspired Maria Goeppert-Mayer and Hans Jensen to propose the shell model were deduced from early experimental observations. The success of the model, at the beginning only able to describe the structure of nuclei near the closed
shells, has been extended in the last decades to the description of well deformed nuclei
with several valence particles in large model...
In my presentation commemorating the 75 years gone since the founding papers of Maria Goeppert-Mayer and Hans Jensen, I will give a personal view of the evolution of the shell model approach to the structure of the atomic nucleus. The virtues and the limitations of the original independent particle model (IPM) and its microscopic justification will be discussed, as well as its fundamental role...
The shell model as a quantum-many-body approach with various correlations due to nucleon-nucleon interactions has shown the shell evolution phenomena in exotic nuclei. I will survey what consequences the same interactions produce for various collective properties. Type II shell evolution in a long chain of Ni isotopes, and the first-order phase transition in Zr isotopes will be mentioned as...
