Thursday 31. January 2013 In Memoriam Paul Kienle (1931-2013)
With the passing of Paul Kienle, former Director of the Stefan Meyer Institute, we lost an eminent scientist and pioneer in subatomic physics. He left us on Tuesday, January 29, 2013, few days after finishing his last scientific...
Wednesday 19. December 2012 SPARC meeting in Vienna
The annual SPARC Collaboration meeting took place in Vienna from November 26 to 28.
Theoretical Studies of Low Energy QCD, Investigated with Exotic Atoms
In 2006 the collaboration with theoreticians of the Atomic Institute of TU Vienna was continued. Theoretical work was done on the development of theoretical models concerning the scientific case of kaonic atoms nuclear clusters which is in lively debate nowa,b since a clear experimental verification is missing. Our institute will participate in new challenging experimental studies on this topic in experiments (AMADEUS@LNF, FOPI@GSI).
An important issue is the extraction of the isoscalar and isovector pion-nucleon scattering lengths. Given the unprecedented values of our PSI experiment on the strong interaction shift and width the correction terms are still an open question. Especially the correction concerning the strong interaction shift is largec. Results of theoretical studiesd were published in 2006.
Outlook
Together with T.E.O. Ericson the extension of the theoretical work on theoretical treatment of our pionic hydrogen data was already discussed in February 2007 and will be continued.
