Pionic and muonic X-ray transitions in liquid helium
G. Backenstoss,G. Backenstoss,J. Egger,J. Egger,T. von Egidy,T. von Egidy,R. Hagelberg,R. Hagelberg,C.J. Herrlander,C.J. Herrlander,H. Koch,H. Koch,H.P. Povel,H.P. Povel,A. Schwitter,A. Schwitter,Ludwig Tauscher,Ludwig Tauscher +17 more
TL;DR: In this paper, the energy shift due to strong interaction effects of the pionic 1s level in liquid 4 He was determined to be −75.7±2.0 eV.
Journal ArticleDOI
Study on antiprotonic atoms of light nuclei and isotopes
H. Poth,G. Backenstoss,I. Bergström,P. Blüm,J.-P. Egger,W. Fetscher,R. Guigas,R. Hagelberg,N. Hassler,C.J. Herrlander,M. Izycki,Herbert Koch,A. Nilsson,P. Pavlopoulos,H.P. Povel,K. Rolli,I. Sick,L. M. Simons,A. Schwitter,J. Sztarkier,L. Tauscher +20 more
TL;DR: In this paper, strong interaction effects in light antiprotonic atoms (N, 16O, 18O, S, S) were studied and a comparison between all existing p-atomic data and an optical model calculation was performed, yielding a set of fit parameters for the potential.
Journal ArticleDOI
K− mass and K− polarizability from kaonic atoms
G. Backenstoss,A. Bamberger,I. Bergström,T. Bunaciu,J. Egger,R. Hagelberg,S. Hultberg,H. Koch,Y. Lynen,H.G. Ritter,A. Schwitter,L. Tauscher +11 more
TL;DR: In this paper, the K − mass was determined from kaonic atomic X-rays from Au and Ba to be 493.691 ± 0.040 MeV, and an upper limit for the polarizability of the k − was found to be 0.020 fm 3 at 90% confidence.
Journal ArticleDOI
Precision determination of the strong interaction shifts and widths of the 1s level in pionic 6Li, 7Li, and 9Be
G. Backenstoss,I. Bergström,J. Egger,R. Hagelberg,C.J. Herrlander,H. Koch,H.P. Povel,R.H. Price,A. Schwitter,Ludwig Tauscher +9 more
TL;DR: The strong interaction shifts of the 1s level in pionic 6Li, 7/Li, and 9Be were determined with an accuracy of better than 1% as mentioned in this paper, and corresponding widths were determined by the same authors with a better than 6% accuracy.
Journal ArticleDOI

H. Poth,R. Abela,G. Backenstoss,P. Blüm,W. Fetscher,R. Hagelberg,M. Izycki,Herbert Koch,A. Nilsson,P. Pavlopoulos,L. M. Simons,L. Tauscher +11 more
TL;DR: In this article, the X-ray spectrum of liquid p-He has been measured and the energies and relative intensities of the Xray transitions feeding the 3d and 2p levels were determined.
