SISAK mini-workshop - preparations for Sg experiments in Japan

Through a Tokai-Riken-Mainz-Oslo collaboration the automated liquid-liquid extraction system SISAK is being combined with an electrolysis cell developed by the Tokai group for performing redox studies on element 106, seaborgium. The workshop will focus on the theoretical and practical foundations for these experiments, with invited contributions from Prof. J. V. Kratz (Univ. Mainz), Dr. V. Pershina (GSI), and Dr. M. Schädel (Tokai). The talks will provide an unique opportunity to get insight into the fascinating chemistry at the very edge of the Periodic Table.

Aim and Scope

The level of the presentations will be aimed at the current Nuclear Chemistry MSc-students. BSc students or others who are considering a similar MSc project are most welcome to attend - likewise if you are just curious about the topic!

Workshop program

The workshop is divided in three parts. The time for presentations listed under each topic should include ample time for questions and discussion.

Part 1 (Wednesday afternoon): Theoretical Fundation

  • 14:30 - Welcome and Introduction (what is "SISAK") (Omtvedt)
  • 14:50 - Historical Flash-Backs of the Automated Liquid-Liquid Extraction System SISAK (Bjørnstad)
  • 15:10 - Theoretical Description of Seaborgium and its Homologues (Pershina)
  • 16:00 - Coffee break
  • 16:20 - Theoretical Considerations for Liquid-Liquid Extraction Experiments of Sg (Pershina)
  • 17:00 - Previous Liquid-Phase Experiments on Seaborgium (Kratz/Schädel)
  • 17:30 - end session

           19:00 - WS dinner


Part 2 (Thursday morning): Experimental Techniques and Challenges

  • 09:00 - The Japan-Oslo SISAK project (Dr. Schädel)
  • 10:00 - Using an Electrolysis Cell with SISAK for Redox Studies (Kratz/Schädel)
  • 10:40 - Coffee break
  • 11:00 - SISAK Challenges in Performing Seaborgium Experiments (Omtvedt)
  • 11:40 - The Link Between Experiments on Super-Heavy Elements and Challenges in Hydrometalurgy (Eriksen)
  • 12:00 - Lunch

Part 3 (Thursday afternoon): Practical Planning and Logistics

  • 13:30 - Discussion about Tokai experiments this spring (incl. Lerum's 3-month stay in Tokai)
  • 14:30 - Discussion about Oslo experiments this spring (post. docs Gupta and Abdo, MSc students Milde and Torèn)
  • 15:30 - Open discussion 
  • 16:00 - End

The last part of the workshop will be discussion about upcoming experiments, which group and people are doing what, equipment and personnel logistics etc. This part have little general for people not already involved in the project.


For organisational reasons we ask that you notify us that you plan to participate in the whole or parts of the workshop. Please send e-mail to to register. Please also indicate if you would like to participate in the workshop dinner and/or lunch.
