[hal-02101685] Shell evolution approaching the N=20 island of inversion : Structure of $^{20}$Mg
14 mai, par ano.nymous@ccsd.cnrs.fr.invalid (A. Matta), A. MattaThe island of inversion for neutron-rich nuclei in the vicinity of N=20 has become the testing ground par excellence for our understanding and modeling of shell evolution with isospin. In this context, the structure of the transitional nucleus Mg29 is critical. The first quantitative (...) -
[hal-02116537] Study of multi-neutron systems with SAMURAI spectrometer
14 mai, par ano.nymous@ccsd.cnrs.fr.invalid (Z.H. Yang), Z.H. YangThe tetraneutron has been drawing the attention of the nuclear physics community for decades, but a firm conclusion on its existence and properties is still far from being reached despite many experimental and theoretical efforts. New measurements have recently been performed at RIBF with the (...) -
[hal-02101665] Transfer reactions induced with $^{56}$Ni : shell gaps and np pairing
14 mai, par ano.nymous@ccsd.cnrs.fr.invalid (A. Georgiadou), A. GeorgiadouThe structure of the unstable doubly magic nucleus $^56$Ni has been investigated by measuring one-and two-nucleon transfer reactions. The radioactive beam of $^56$Ni was produced at GANIL-Caen, France at 30 MeV/u by means of the LISE spectrometer. The experimental setup used consists of the (...) -
[hal-01669659] Density Functional approach for multi-strange hypernuclei : competition between $\Lambda$ and $\Xi^{0,-}$ hyperons
13 mai, par ano.nymous@ccsd.cnrs.fr.invalid (J. Margueron), J. MargueronThe question of the competition between Λ and Ξ0,− in the ground state of multistrange hypernuclei is addressed within a nonrelativistic density functional approach, partially constrained by ab initio calculations and experimental data. The exploration of the nuclear chart for 10 Z 120 as a (...) -
[hal-01952664] How Robust is the $N = 34$ Subshell Closure ? First Spectroscopy of $^{52}$Ar
13 mai, par ano.nymous@ccsd.cnrs.fr.invalid (H.N. Liu), H.N. LiuThe first γ-ray spectroscopy of Ar52, with the neutron number N=34, was measured using the K53(p,2p) one-proton removal reaction at ∼210 MeV/u at the RIBF facility. The 21+ excitation energy is found at 1656(18) keV, the highest among the Ar isotopes with N>20. This result is the first (...)
