Present Situation
Next Goals
Actions within FINUPHY
Heavy and Superheavy Elements
Nuclear Chart March 2004
Elements 113, 115 added by Dubna
Elements 113, 115 added by Dubna
Elements 110,111,112confirmed by RIKEN
Elements 110,111,112confirmed by RIKEN
T1/2 > 10s- Chemistry- Traps
Production Cross Sections208Pb,209Bi targets
48Ca beams
Z >110 is picobarn physicsDubna data with 48Ca do not follow systematics as observed for other reactions
Promising and challenging !
Actions
Organisation and support of workshops and conference participation
• to see frontiers and problems
• define strategies
• strengthening European collaboration
• improve infrastructures
Next goals The Dubna data open great perspectives for SHE research
Problems:
A, Z identification
Cross sections not understood
Z = 112 results confusing, Berkeley results negative
Needed:
Experiments at other labs (GSI)
Direct mass identification -> mass spectrometer, trap,
new detectors
Direct Z identification -> picobarn chemistry
Reaction studies
Improve GSI infrastructure for picobarn-level research
Towards Femtobarn Chemistry
Actinides 2003 (Berkeley)
and Workshop on GBS and Chemsep
Participation supported from FINUPHY
Conclusion:
A gas filled separator at GSI dedicated for
chemistry experiments will be designed
Tours Symposium: GSI-GANIL-RIKEN: SHE-session
TOURS SYMPOSIUM ON NUCLEAR PHYSICS V: Tours 2003
AIP Conference Proceedings 704Conference Location and Date: Tours, France, 26-29 August 2003
This book covers the latest developments in synthesizing super-heavy elements at RIKEN and GSI, and in theories of fusion-fission dynamics; studies of nuclei .......
Review the field-> Strengthen European collaborations-> Attract young scientists
Note: the Japanese results are of great value for GSI and the field
Develop strategies for GSI research and strenghten community
Workshop on
The Futureof Superheavy Element ResearchFebruary 17 - 18, 2004Gesellschaft für SchwerionenforschungDarmstadt, Germany
S. Hofmann, 60th birthday
Results:Improvement of GSI infrastructure-> Intensity upgrade-> Chemsep (gas filled separator for chemistry) design starts-> New techniques: SHIPTRAP, detailed spectroscopy of SHE
