X-ray spectroscopy is an advantageous tool for investigation of the shift and width of the energy levels in kaonic atoms, evoked due to strong interaction between nucleus and kaon. In order to study the 2p level shift in kaonic 3 He , the X-ray transition 3 p →2 d in liquid kaonic 3 He will be measured with a precision of <2 eV in the E17 experiment at J-PARC. To reach this desired precision, a well designed setup, in-situ calibration and state-of-the-art semiconductor detectors will be used. The idea and the preparation status of the whole setup will be reported in this article.

The Hotbird is a state of the art X-ray laboratory for advanced materials characterisation, installed at ITN since 1999. Several major improvements in its capabilities have been implemented. On the one hand, new hardware developments have extended the applications that can be studied and on the other hand, new software has enabled both enhanced automated control of the system, and improved data analysis that leads to extraction of further precise information from the data. One improvement was the implementation of the x-ray reflectometry (XRR) technique, which is a major expansion of the Hotbird capabilities. XRR is well-suited to characterise film thickness and roughness with high resolution. Furthermore, several optics improvements, such as a Göbel mirror and monochromators were introduced. The combination of this optics allows one to use either a higher intensity beam (orders of magnitude better) or a higher resolution beam configuration. A new high-temperature chamber was developed, which allows one to perform in-situ experiments with excellent temperature control up to 800 °C, in all possible configurations. Data simulation/fitting analysis software for XRR was developed. Also, to control the diffractometer and perform experiments, a new user-friendly software package was developed. In order to illustrate the Hotbird capabilities improvements, several experimental examples will be described.

Experiments on kaonic atoms between 1972 and 1982 at four world-class laboratories established a data base comprising of 24 species along the periodic table. Here we present a short overview of methods for obtaining strong interaction information from these results. Early straight-forward phenomenological analyses and also more sophisticated approaches led to ambiguities and open problems. Using state-of-the-art K̄-nucleon amplitudes plus a phenomelogical multinucleon term can fit the data only when sub-threshold energies are considered. Remaining ambiguities are removed with the help of old bubble-chamber experiments on single-nucleon absorption fraction at threshold.

Theory And Experiment

We have measured the Balmer-series x-rays of kaonic 4 He atoms using large-area silicon drift x-ray detectors (SDDs) in order to study the low-energy [Formula: see text]-nucleus strong interaction. The energy of the 3d → 2p transition was determined to be 6467 ± 3( stat ) ± 2( syst ) eV . The resulting strong-interaction energy-level shift is in agreement with theoretical calculations, thus eliminating a long-standing discrepancy between theory and experiment.
