Line shape analysis of the K transition in muonic hydrogen
D. S. Covita, D. F. Anagnostopoulos, H. Fuhrmann +19
The K transition in muonic hydrogen was measured with a high-resolution crystal spectrometer. The spectrum is shown to be sensitive to the ground-state hyperfine splitting, the…
Measurement of the charged pion mass using a low-density target of light atoms
M Trassinelli, D. F. Anagnostopoulos, G Borchert +10
We present a new evaluation of the negatively charged pion mass based on the simultaneous spec-troscopy of pionic nitrogen and muonic oxygen transitions using a gaseous target comp…
Measurement of the charged pion mass using X-ray spectroscopy of exotic atoms
M Trassinelli, D. F. Anagnostopoulos, G. Borchert +10
The transitions in pionic nitrogen and muonic oxygen were measured simultaneously by using a gaseous nitrogen-oxygen mixture at 1.4\,bar. Due to the precise knowledge of th…
Hadronic shift in pionic hydrogen
M. Hennebach, D. F. Anagnostopoulos, A. Dax +12
The hadronic shift in pionic hydrogen has been redetermined to be \,eV by X-ray spectroscopy of ground state transitions applying v…
Precision determination of the dpi -> NN transition strength at threshold
Th. Strauch, F. D. Amaro, D. F. Anagnostopoulos +16
An unusual but effective way to determine at threshold the dpi -> NN transition strength is to exploit the hadronic ground-state broadening in pionic deuterium, accessible by x-ray…
Line shape of the muH(3p - 1s) hyperfine transitions
D. S. Covita, D. F. Anagnostopoulos, H. Gorke +13
The (3p - 1s) X-ray transition to the muonic hydrogen ground state was measured with a high resolution crystal spectrometer. A Doppler effect broadening of the X-ray line was estab…
