Prediction for a four-neutron resonance
A. M. Shirokov, G. Papadimitriou, A. I. Mazur +3
We utilize various {\em ab initio} approaches to search for a low-lying resonance in the four-neutron () system using the JISP16 realistic interaction. Our most accurate p…
The No-Core Gamow Shell Model: Including the continuum in the NCSM
B. R. Barrett, G. Papadimitriou, N. Michel +1
We are witnessing an era of intense experimental efforts that will provide information about the properties of nuclei far from the line of stability, regarding resonant and scatter…
Nucleon-nucleon resonances at intermediate energies using a complex energy formalism
G. Papadimitriou, J. P. Vary
We apply our method of complex scaling, valid for a general class of potentials, in a search for nucleon-nucleon S-matrix poles up to 2 GeV laboratory kinetic energy. We find that…
Nucleon-nucleon scattering with the Complex Scaling Method and realistic interactions
G. Papadimitriou, J. P. Vary
We demonstrate the validity of the complex scaling method for realistic strong, non-local, nucleon- nucleon interactions by comparing the deuteron bound state and nucleon-nucleon s…
Ab-initio No-Core Gamow Shell Model calculations with realistic interactions
G. Papadimitriou, J. Rotureau, N. Michel +2
No-Core Gamow Shell Model (NCGSM) is applied for the first time to study selected well-bound and unbound states of helium isotopes. This model is formulated on the complex energy p…
Charge radii and neutron correlations in helium halo nuclei
G. Papadimitriou, A. T. Kruppa, N. Michel +3
Within the complex-energy configuration interaction framework, we study correlations of valence neutrons to explain the behavior of charge radii in the neutron halo nuclei …
