The workshop aims at bringing together researchers from various subfields of this larger community to celebrate the nuclear isomers centenary. Although postponed by one year due to the Covid-19 pandemic, the meeting remains timely. The isomer community is preparing for major new experimental facilities that are under construction and soon to be commissioned, for example FAIR, ELI-NP, FRIB and HIAF. These will offer exceptional cross-disciplinary opportunities. We are meeting to discuss these opportunities and to prepare for them in a strategic manner. The workshop aims at synergy and cross-fertilizing effects, that will bring a new impetus to isomer research.
