E. Khan03/09/2018, 14:30Relativistic energy density functionnal approaches are able to describe on a common ground quantum liquid and cluster states in nuclei. We will first show how the experimental observables related to clusterisation are described with this approach. The study of the localisation of the nucleonic wave-functions in nuclei will also be undertaken in order to provide a deep understanding of the...Go to contribution page

Prof. Peter Schuck (Institut de Physique Nucleaire Orsay)03/09/2018, 15:15Alpha clustering in nuclear systems has known an extraordinary growth in activity over the last 15 years or so. I have strongly participated in the theoretical developments of alpha clustering and with my collaborators I have for example proposed that the Hoyle state in 12C can be considered as an alpha particle condensate. This theory explains all known data of the Hoyle state, for instance...Go to contribution page

Dr Massimo Papa (INFN)03/09/2018, 15:55One of the most important and intriguing problems in studying Heavy Ion collisions at the Fermi energies is to recover information directly linked to the dynamical stage of the reaction without the blurring effects of later stages associated the statistical decay of the hot source. In this case the obtained results can give clear information on the effective interactions governing the...Go to contribution page

Dr Zsolt Podolyak (University of Surrey)04/09/2018, 14:00Information gained on neutron-rich N~126 nuclei is essential for the understanding of nuclear structure in heavy nuclei. Studies around doubly magic systems allow direct tests of the purity of shell model wave functions. From a longer-term perspective, experiments in this region pave the way toward the proposed nuclear-astrophysical r-process waiting point nuclei along the N = 126 shell...Go to contribution page

Dr Esra Yรผksel (Department of Physics, Faculty of Science, University of Zagreb, Croatia, Department of Physics, Yildiz Technical University, 34220 Esenler, Istanbul, Turkey)04/09/2018, 14:45The nuclear weak interaction processes (beta decay, electron capture, neutrino-nucleus scattering etc.,) is known to play an important role in the supernovae evolution and formation of the chemical elements. The calculation of these processes necessitates accurate knowledge on the spin-isospin excitations as well as the ground state properties of nuclei [1,2]. In this framework, the...Go to contribution page

Mr Vรญctor Vaquero Soto (CSIC)04/09/2018, 15:05The nuclei around the doubly magic nucleus 132Sn (N=82 and Z=50) are of great interest both for nuclear structure investigations and nuclear astrophysics. Studying these systems, information about the evolution of nucleon-nucleon correlations, quadrupole collectivity and single-particle energies can be obtained. New experimental information allows to test different nuclear models and examine...Go to contribution page

Marco Siciliano (LNL)04/09/2018, 15:25In the last years the robustness of the proton shell closure Z=50 has been studied when N=50 is approached: the excitation energy together with the reduced transition probabilities of the low-lying states provides a clear evidence of the shell evolution along the whole Sn isotopic chain. However, the presence of low-lying isomers has limited the investigation of the electromagnetic properties...Go to contribution page

At these low densities cluster correlations are predicted, with alpha clusters being of special interest. The isotopes of Sn are convenient examples for an experimental test of predictions from a generalized relativistic density functional...Go to contribution page

Irene Zanon (INFN LNL)04/09/2018, 16:05Shape coexistence is a characteristic phenomenon of finite many-body quantum systems where different nuclear shapes coexist within the typical energy range of nuclear excitations. The principle behind this phenomenon is the contrast between two different forces: on one hand valence nucleons and np-nh excitations drive the nucleus to collective configurations; on the other hand, pair forces and...Go to contribution page

Dr Pastore Alessandro (University of York)06/09/2018, 14:00Any given finite-range two-body interaction can be developed by means of a simple Taylor series in momentum space. This is the basic idea presented by Skyrme in its original paper. Truncating the Taylor series at second order in gradients, we obtain the standard Skyrme interaction (N1LO). In this talk I will discuss the truncation at 4th and 6th order in gradients and the new family of...Go to contribution page

Mr Ian Murray (Institut de Physique Nucleaire, IN2P3-CNRS, Universite Paris-Sud)06/09/2018, 14:25The shell model lays an impressive foundation for broad understanding of nuclear systems. For the most exotic nuclei, universal mechanisms drive shell evolution from established structures, such as the disappearance of canonical magic numbers. The spin-isospin parts of the nucleon-nucleon interaction, and specifically, the monopole part of the tensor force between different orbits is a strong...Go to contribution page

Dr Franck Delaunay (LPC Caen, France)06/09/2018, 14:45Beta-decay spectroscopy is one of the most useful tools for the study of nuclear structure. In exotic nuclei beta-decay is often followed by the emission of delayed particles, a process which becomes the dominant decay channel when approaching the driplines. In the most exotic species, the emission of two or more delayed particles can also occur with a significant probability. Whereas the...Go to contribution page

Prof. Joaquin Gomez Camacho (CNA)06/09/2018, 17:00The study of the structure of normal, well bound nuclei, can be carried out by populating discrete excited states in a reaction, and studying their gamma decay. Here, the nuclear reaction is just a mechanism to populate excited states, whose properties such as energy and decay probabilities are independent of the reaction that produced it. Exotic nuclei, weakly bound, have few (if any)...Go to contribution page

Prof. Elena Botta (TO)06/09/2018, 17:25The Charge Symmetry of the strong interaction requires that nn and pp interaction strengths are equal. As a consequence, the energy levels of nuclear isospin multiplets are expected to be identical, after correcting for the Coulomb energy difference. The breaking of this symmetry manifests itself in experiments at a level of ~0.07 MeV for the NN interaction in normal, not strange,...Go to contribution page
