Heavy and Superheavy Elements

Naming of element 110Darmstadtium

Element 111 approved by IUPAC

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
