3. From Global E1 Strength to the Pygmy Dipole: A Shell-Model Perspective on Light Nuclei

Oscar Le Noan (IPHC - CNRS - University of Strasbourg)

Oral Presentation

Understanding how atomic nuclei respond to electromagnetic perturbations provides key insights into their structure and dynamics.
In this talk, I will address nuclear response functions, focusing on the electric dipole (E1) mode, one of the most fundamental collective excitations in nuclei. Particular attention will be paid to the Pygmy Dipole Resonance (PDR), an exotic low-energy mode...

54. Discrete Non-Orthogonal Shell Model: from mid-mass to heavy deformed nuclei

M. Duy Duc Dao (IPHC Strasbourg)

Oral Presentation

We present an extension of the Discrete Non-Orthogonal Shell Model [1, 2] within a Variation After Projection approach [3] recently developed at IPHC, Strasbourg. This method is an alternative to the exact shell-model diagonalization [4] using non-orthogonal many-body expansions combined with symmetry restoration techniques [5]. We discuss the prospective of the new method for applications...
