Virtual workshop on the "Atomic Structure of Actinides & Related Topics"

26 May 2021, 09:00 → 28 May 2021, 18:00 Europe/Berlin

Dear Colleagues,

We would like to draw your attention to the upcoming virtual workshop on the "Atomic Structure of Actinides & Related Topics" and cordially invite you to attend.

The actinide series exhibits a remarkable transition in terms of applied and fundamental research, as it hosts the heaviest naturally occurring elements and fades into fully man-made elements. Concerning basic atomic information, the actinide series is at the edge of current knowledge and still lacks some fundamental information. In this context, we would like to offer an event that will bring together scientists from theory and experiment to report on recent advances in the study of actinide atomic structure and related research areas, including but not limited to:

• Production of the actinides
• Atomic structure theory
• Spectroscopy approaches
• Transport properties
• Nuclear physics
• Nuclear medicine

For the scientific program, please visit our Timetable. Please note that due to the current situation, the workshop will be completely virtual.

Best regards and we are looking forward to welcoming you in May 2021!

                   Mustapha Laatiaoui and Sebastian Raeder
