Shortcuts to nuclear structure: lessons in Hartree-Fock, RPA, and the no-core shell model
Calvin W. Johnson, Ionel Stetcu
While the no-core shell model is a state-of-the-art microscopic approach to low-energy nuclear structure, its intense computational requirements lead us to consider time-honored ap…

Electromagnetic transitions with effective operators
Ionel Stetcu, Bruce R. Barrett, Petr Navratil +1
In the no-core shell model formalism we compute effective one- and two-body operators, using the Lee-Suzuki procedure within the two-body cluster approximation. We evaluate the val…
