Gamow shell model description of the hypernuclei
Alan Cruz Dassie, Emiko Hiyama, Nicolas Michel +1
Hypernuclear physics studies baryon interactions and the structure of exotic atomic nuclei, where strangeness plays a key role in dense matter. High-resolution -ray spectroscopy…
Search for the Double Poles of the Scattering Matrix in Light Nuclei
David Cardona Ochoa, Marek Płoszajczak, Nicolas Michel
Exceptional points (EPs) are non-Hermitian degeneracies at which two eigenvalues and their eigenvectors coalesce, producing a defective Hamiltonian and a double pole of the -mat…
N(p,O factor and the puzzling solar composition problem
G. X. Dong, X. B. Wang, N. Michel +1
In stellar hydrogen burning, the CNO cycle dominates, with the N(p,O reaction being the slowest process. Consequently, this reaction critically influences the solar…
Unfolding of exotic near-threshold structure and decay dynamics in B
A. Volya, S. M. Wang, M. Płoszajczak +1
Neutron-rich boron isotopes provide a valuable testing ground for threshold-driven structure and reaction phenomena, including halo formation and exotic decay modes. In particular,…
Gamow shell model description of exceptional point in Li
David Cardona Ochoa, Marek Płoszajczak, Nicolas Michel
We report the first identification of an exceptional point (EP) within the Gamow Shell Model in the Coupled Channels representation (GSM-CC). In the spectrum of Li, an EP is…
Double pole -matrix singularity in the continuum of Be
David Cardona Ochoa, Marek Płoszajczak, Nicolas Michel +1
The double pole singularity of the -matrix, the so-called exceptional point, associated with the doublet of resonances in the spectrum of Be has been identified in…
Unbound neutron strength in C and the N=16 shell gap
J. Lois-Fuentes, B. Fernández-Domínguez, F. Delaunay +61
Significant continuum strength has been observed to be populated in C produced in the d(C,p) reaction at a beam energy of 17.2~MeV/nucleon. The strength appears at gr…
FNe reaction rate and the puzzling calcium abundance in metal poor stars
G. X. Dong, X. B. Wang, N. Michel +1
The FNe reaction is the only process to break out of the CNO cycle at temperature below 0.1 GK and may serve as the origin of calcium in first generation of st…
Clusterization in nuclear states at the edge of stability
J. P. Linares Fernandez, N. Michel, M. Płoszajczak
The open quantum system eigenstate in the vicinity of low-energy decay channel may mimic its features, in particular the characteristic clustering properties of the decay channel.…
Astrophysical S-factor for LiBe in the coupled-channel Gamow shell model
G. X. Dong, K. Fossez, N. Michel +1
We have applied the Gamow shell model (GSM) in the coupled-channel representation to study the astrophysical -factor for the proton radiative capture reaction of Li. Reactio…
Description of the proton and neutron radiative capture reactions in the Gamow shell model
K. Fossez, N. Michel, M. Płoszajczak +2
We formulate the Gamow shell model (GSM) in coupled-channel (CC) representation for the description of proton/neutron radiative capture reactions and present the first application…
Simplified modeling of cluster-shell competition in Ne and Mg
N. Itagaki, J. Cseh, M. Płoszajczak
We investigate properties of the Generator Coordinate Method (GCM) on a collective basis of Antisymmetrized Quasi-Cluster (AQC) states to describe the cluster-shell competition in…
Structure of Exotic Nuclei
J. Dobaczewski, N. Michel, W. Nazarewicz +2
The progress in the modeling of exotic nuclei with an extreme neutron-to-proton ratio is discussed. Two topics are emphasized: (i) the quest for the universal microscopic nuclear e…
Nuclear Multifragmentation in the Non-extensive Statistics - Canonical Formulation
K. K. Gudima, A. S. Parvan, M. Ploszajczak +1
We apply the canonical quantum statistical model of nuclear multifragmentation generalized in the framework of recently proposed Tsallis non-extensive thermostatistics for the desc…
Multifragmentation of non-spherical nuclei
A. Le Fevre, M. Ploszajczak, V. D. Toneev
The shape influence of decaying thermalized source on various characteristics of multifragmentation as well as its interplay with effects of angular momentum and collective expansi…
