First Observation of 27,28O

First Observation of 27,28O Subjecting a physical system to extreme conditions is one of the means often used to obtain a better understanding and deeper insight into its organization and structure. In the case of the atomic nucleus, one such approach is to investigate isotopes that have very different ratios of the numbers of neutrons […]

IN2P3 awards five students a scholarship for excellence in the two infinities

IN2P3 awards five students a scholarship for excellence in the two infinities Five Master’s students were received in the Salon d’Honneur at CNRS headquarters on January 29 to receive the very first “Bourses d’Excellence des Deux Infinis” from Reynald Pain. This new IN2P3 program aims to support young people in their second year of Master’s […]

Intruder states and shape coexistence beyond N=50 close to 78Ni studied by neutronknockout at RIBF-RIKEN

PhD Defense 2023 november, 23 Léo Plagnol Intruder states and shape coexistence beyond N=50 close to 78Ni studied by neutron knockout at RIBF-RIKEN The recent spectroscopy of 78Ni together with indications of shape coexistence just below the N=50 shell closure for 79Zn suggests that deformed intruder configurations could play a crucial role in low-energy structure […]

A Unified Equation of State for Neutron Stars and Core-Collapse Supernovae

Defense thesis Sept. 18 2023 A Unified Equation of State for Neutron Stars and Core-Collapse Supernovae Hoa DINH THI **Abstract:**This thesis aims to study the interior properties of isolated, non-accreting, and non-rotating (proto-)neutron stars. For this purpose, the meta-modeling technique was employed to compute the properties of nuclear matter, while the inhomogeneities in the crust […]

One more step towards the observation of the tetraneutron

Representation of a tetraneutron. The unambiguous observation of this system composed of 4 neutrons, sheds new light on the mechanisms of cohesion in the atomic nucleus or neutron stars. Credit: CNRS/IN2P3 A resonance structure compatible with a quasi-bound tetraneutron has been observed by scientists of the SAMURAI collaboration in RIKEN, Japan, in which a team […]
