Proceedings of 13th international conference on nucleus-nucleus collisions

The 13th International Conference on Nucleus-Nucleus Collisions (NN 2018) was held in December 4th (Tue.) to 8th (Sat.) at the Sonic City Hall in Omiya, Saitama, Japan. We had 219 participants from 14 countries or areas. There were 38 plenary talks, 131 parallel talks (including 28 invited talks) and 36 posters in ten parallel sessions as 'Fusion and Fission', 'Heavy and Superheavy Elements', 'Nuclear Structure and Dynamics', 'Nuclear Astrophysics', 'Equation of State of Nuclear and Quark Matter under Extreme Conditions', 'Collision Dynamics at Medium to Relativistic Energies', 'Hadron Physics', 'New Facilities', 'Nuclear Methods for Pure and Applied Sciences', and 'Nuclear Energy and Applications of Nuclear Science and Technologies'. The full program and presentation files are available online at the conference website (http://nn2018.riken.jp/), with the conference photo. All contributed papers of this proceedings were peer-reviewed through the JPS online-reviewing system. Satellite workshops: 'Tsukuba-CCS workshop on microscopic theories of nuclear structure and dynamics' (https://www.ccs.tsukuba.ac.jp/ccs-workshop2018), 'ImPACT International Symposium on New Horizons of Partitioning and Transmutation Technologies with Accelerator System' (https://www.jst.go.jp/impact/hp_fjt/news/20181202.html), and 'Recent advances in nuclear structure physics 2018 (RANSP2018)' (https://www.yukawa.kyotou.ac.jp/seminar/s52455), were held and many related topics to the nucleus-nucleus collisions were discussed. 86 papers of the entitled conference are indexed individually.
