Shapes and Symmetries in Nuclei: from Experiment to Theory (SSNET'18 Conference)
The SSNET 2018 Conference, hosted by the Centre de Sciences Nucléaires et Sciences de la Matière (CSNSM) in Orsay, was held at the I2BC auditorium on the CNRS campus in Gif-sur-Yvette, France, from November 5th to the 9th, 2018.
As in the previous -and successful!- editions, the conference aims at strengthening the international collaboration between the nuclear structure physicists from France, Europe and other laboratories all around the world. It allowed fruitful discussions on recent experimental and theoretical aspects of nuclear structure related to the manifestation and description of the various shapes and geometrical symmetries of the nucleus as well as other symmetries and symmetry breaking.
Organizing committee: Alain Astier, Isabelle Deloncle, Etienne Dupont, Amel Korichi, Radomira Lozeva, BingFeng Lv, Costel Petrache (chair), Jerzy Dudek (co-chair)
Conference secretary: Émilie Bonnardel
