Program of the conference ............................................................................... 114 4 Chapter 1 Executive Summary A. Maj The H. Niewodniczański Institute of Nuclear Physics PAN, Kraków, Poland and K. Rusek Heavy Ion Laboratory, University of Warsaw, Warsaw, Poland This Report presents the status and perspectives of low-energy nuclear physics research in Poland. It has become a tradition that the society of Polish nuclear physicists periodically summarizes the community’s achievements and draws up plans for the future. The very first such report was prepared by a team of scientists led by Professor Jerzy Jastrzębski and published by the Polish Nuclear Physics Network under the title “Nuclear Physics in Poland 1996-2006”. The next one, entitled “Long-Range Plan of Polish Nuclear Physics in the years 2007-2016” was prepared by the Commission of Nuclear Physics, the Advisory Board of the National Atomic Energy Agency of Poland. The team of editors was led by Professor Jan Styczeń. A few years later, this Commission, led this time by Professor Krzysztof Rusek, published the “Long-Range Plan of Polish Nuclear Physics and Nuclear Methods, 2010-2020”. The present Report is the result of a two-day conference entitled “The future of low-energy nuclear physics in Poland and the development
