Karlsruhe Nuclide Chart – a tradition in progress for nuclear data

The Karlsruhe Nuclide Chart is a well-known nuclear data collection used in education and research institutions worldwide. This paper summarises its content from 1958, with data on 1517 experimentally observed nuclides, to the latest 2022/23 edition with data on 4122 nuclides. The paper also provides an overview of the data content of the latest edition with emphasis on the data sources. The unique features of this nuclide chart are the compact presentation of the most essential and up-to-date nuclide data in small, 1.5 × 1.5 cm nuclide boxes and the availability in different printed formats. This compact data presentation allows the Chart to supplement educational and research materials in the last 65 years. In the past eleven years, the Chart’s booklet has been extended by 100 simplified decay schemes for nuclides of particular interest to understand the decay processes in more detail.
