Preface

It was organized by the Nuclear Data Section, Division of Physical and Chemical Sciences, of the International Atomic Energy Agency (IAEA), following the cancellation of the workshop that was scheduled to be held in Athens in 2020 due to the fallout from the COVID-19 pandemic.In keeping with the tradition of past workshops held in Yosemite (2007), Bordeaux (2009), Prague (2011), So Paulo (2013), Tokyo (2015), and Berkeley (2018), the workshop brought together 90 participants from 24 countries to share developments in and exchange know-how on compound-nuclear reactions and related topics.A total of 52 talks (12 keynote; 16 invited; 24 contributions) and 30 poster presentations were included in the program covering different facets of compound nuclear reactions such as reaction mechanisms of nucleons and complex particles, nuclear fission, surrogate methods and R-matrix theory, the optical model, statistical properties such as level densities and photon strength functions, the interplay between nuclear structure and nuclear reactions, measurements and facilities, and applications in nuclear astrophysics.To emphasize the significance of compound nuclear reactions in nuclear technologies and applications, which are supported by international programs coordinated by the IAEA, two sessions focused on nuclear data evaluation methods and their outcomes.Another highlight of the workshop was a special session dedicated to the late Eric Bauge (CEA, France) who passed away suddenly in May 2022.In this session, titled "Building Bridges", eight presentations honoured Eric's significant contributions to international and cross-disciplinary collaboration.
