A series of International Symposia "Atomic Cluster Collisions: structure and dynamics from the nuclear to the biological scale" started in 2003, and ten ISACC conferences have been held so far. The latest ISACC conference was organized in October 2021 jointly with the sixth International Conference "Dynamics of Systems on the Nanoscale" (DySoN) under the title "DySoN-ISACC 2021".

Most ISACC conferences were satellites of the International Conferences on Photonic Electronic and Atomic Collisions (ICPEAC). The ISACC 2023 will be held just before the ICPEAC 2023 conference (Ottawa, Canada, July 25-August 01, 2023).

The ISACC conference series promotes the growth and exchange of scientific information on the structure, properties and dynamics of complex nuclear, atomic, molecular, cluster, nanoscopic and biological systems studied primarily by means of photonic, electronic and atomic collisions. Particular attention is devoted to dynamical phenomena and many-body effects taking place in clusters, nanostructures, molecular and biological systems. These include problems of fusion and fission, fragmentation, collective electron excitations, phase transitions, radiation damage, and many more. Both experimental and theoretical aspects of cluster physics uniquely placed between nuclear physics on one hand and atomic, molecular and solid state physics on the other will be the subject of the ISACC 2023 symposium. Particular attention at the Symposium will be devoted to the utilization of advanced computational techniques and high-performance computing for studying the aforementioned phenomena and effects. Links of the ISACC topics to novel and emerging technologies will be an important focus of the ISACC 2023.

Finally, ISACC 2023 will provide a platform to host discussions about current research, technological challenges, and related initiatives within the ISACC Topical Areas.

ISACC is a biennial conference that focuses on the following subjects:

  • Structure and dynamics of atomic clusters and nanoparticles
  • Structure and dynamics of biomolecules
  • Reactivity and nanocatalysis
  • Clustering in systems of various dimensionality and degrees of complexity
  • Electron-, photon- and ion collisions with clusters and nanoparticles
  • Electron-, photon- and ion collisions with biomolecules
  • Complex collision, radiative and fragmentation processes
  • Clusters and biomolecules in external fields: electric, magnetic, laser etc.
  • Cluster and biomolecular research with Free Electron Lasers
  • Related technological and medical applications
