Towards Model Independent and Perturbative Shell Model Effective Interactions

Conventional microscopic calculations of effective shell model interactions in nuclei are model dependent and non-perturbative. Through the use of renormalization group methods, I describe an approach that eliminates much of the model dependence arising from the particular model of the free space nucleon-nucleon interaction used as microscopic input for many-body calculations. Perturbative calculations of shell model interactions are shown to exhibit improved convergence properties in several nuclei.
