Nuclear ab initio spectroscopy

Organizers:  T. Duguet (CEA DRF DPhN, contact), M. Frosini (CEA DES IRESNE), G. Hagen (Oak Ridge Nat. Lab), R. Roth (TU Darmstadt)
contact: thomas.duguet [at] cea.fr

 

 

The main goals of the workshop are:
1. to review existing ab initio approaches to nuclear spectroscopy in light- and medium-mass nuclei,
2. to discuss limitations of current methods and possible workarounds.
