Shell-Model Analyses of Weak and Electromagnetic Data: The Interplay of Many-Body and Single-Nucleonic Features

摘要: Our understanding of nuclear structure suggests that the values electromagnetic and weak observables measured in physics experiments reflect an interplay between “universal” properties neutrons protons as they exist finite nuclei highly state-specific coherent features many-body wave functions which describe how these are combined into individual eigenstates. Only for “single-particle” “single-hole” adjacent to doubly-magic can aspects such be approximately factored out a trivial fashion. For great majority nuclei, implications experimental data about general emerge only after idiosyncrasies different matrix elements understood extracted. Since we do not have, priori, quantitatively accurate theories structure, confidence factorisation from single-nucleonic is obtained by internally consistent analyses extensive sets data.
