Description

Exotic hadronic atoms, especially pionic and kaonic hydrogen atoms, in which one of these meson replaces the electron, play a unique role, because their study allows to experimentally investigating the strong interaction, described by Quantum Chromo Dynamics (QCD). Due to the strong interaction the ground state is shifted from his pure electromagnetic value and broadened due to absorption of the meson into the nucleus. Shift and broadening are determined due to the measurement of the X-ray transition energy from 2p to 1s state.
Depending on the exotic atom under investigation different detector systems were developed.
An overview of specially developed high-resolution X-ray detector systems for pionic and kaonic atom measurements will be given.
