Towards Model Independent and Perturbative Shell Model Effective Interactions

Microscopic calculations of the effective shell model interaction in nuclei are typically model dependent and highly non-perturbative. Through the use of renormalization group and effective theory methods, I describe a new approach that eliminates much of the model dependence arising from the particular model of the free space nucleon-nucleon interaction used as input. Moreover, when combined with the methods developed by Haxton and Luu, one obtains a perturbative and model independent calculation of the effective shell model interaction in A=3 nuclei.
