In-beam measurement of the hydrogen hyperfine splitting - towards antihydrogen spectroscopy
M. Diermaier, C. B. Jepsen, B. Kolbinger +6
Antihydrogen, the lightest atom consisting purely of antimatter, is an ideal laboratory to study the CPT symmetry by comparison to hydrogen. With respect to absolute precision, tra…
First application of superconducting transition-edge-sensor microcalorimeters to hadronic-atom x-ray spectroscopy
S. Okada, D. A. Bennett, C. Curceanu +35
High-resolution pionic-atom x-ray spectroscopy was performed with an x-ray spectrometer based on a 240-pixel array of superconducting transition-edge-sensor (TES) microcalorimeters…
Towards Measuring the Ground State Hyperfine Splitting of Antihydrogen -- A Progress Report
C. Sauerzopf, A. Capon, M. Diermaier +28
We report the successful commissioning and testing of a dedicated field-ioniser chamber for measuring principal quantum number distributions in antihydrogen as part of the ASACUSA…
Low-energy Antikaon Interaction with Nuclei: The AMADEUS Challenge
Johann Marton, Massimilliano Bazzi, Giovanni Bellotti +25
The low-energy strong interaction of antikaons (K-) with nuclei has many facets and rep- resents a lively and challenging research field. It is interconnected to the peculiar role…
-series X-ray yield measurement of kaonic hydrogen atoms in a gaseous target
M. Bazzi, G. Beer, G. Bellotti +29
We measured the -series X-rays of the exotic atom in the SIDDHARTA experiment with a gaseous hydrogen target of 1.3 g/l, which is about 15 times the of hy…
Strong interaction studies with kaonic atoms
J. Marton, M. Bazzi, G. Beer +30
The strong interaction of antikaons with nucleons and nuclei in the low-energy regime represents an active research field connected intrinsically with few-body physics. There are i…
Spontaneously emitted X-rays: an experimental signature of the dynamical reduction models
C. Curceanu, S. Bartalucci, A. Bassi +29
We present the idea of searching for X-rays as a signature of the mechanism inducing the spontaneous collapse of the wave function. Such a signal is predicted by the continuous spo…
Precision X-ray spectroscopy of kaonic atoms as a probe of low-energy kaon-nucleus interaction
H. Shi, M. Bazzi, G. Beer +29
In the exotic atoms where one atomic electron is replaced by a , the strong interaction between the and the nucleus introduces an energy shift and broadening of…
Structure near ++ threshold in the in-flight He reaction
PARC E15 Collaboration, Y. Sada, S. Ajimura +69
To search for an S= -1 di-baryonic state which decays to , the reaction was studied at 1.0 GeV/. Unobserved neutrons were kinematically ide…
