[en] A method is presented by which quick and reliable energy loss data for heavy ions in solids can be determined. If the elastic scattering cross section as a function of the energy is known, then it is possible to determine a larger energy range of the differential energy loss from one single measurement.

[en] Full text: Correlated many-particle dynamics in Coulombic systems, which is one of the unsolved fundamental problems in AMO-physics, can now be experimentally approached with so far unprecedented completeness and precision. The recent development of the COLTRIMS technique (COLd Target Recoil Ion Momentum Spectroscopy) provides a coincident multifragment imaging technique for eV and sub-eV fragment detection. In its completeness it is as powerful as the bubble chamber in high energy physics. In recent benchmark experiments quasi snapshots (duration as short an atto-sec) of the correlated dynamics between electrons and nuclei has been made for atomic and molecular objects. This new imaging technique has opened a powerful observation window into the hidden world of many-particle dynamics. The principle of the new reaction microscope (synonym: COLTRIMS) will be presented. If imaging detectors based on fast delay-line position read-out are used multi-hit detection is possible. Even two particles hitting the detector at the 'same' instant (Δt < 1 ns) can simultaneously be detected. The number of detected multi-hits is practically only limited by the electronics needed to store in event mode all information. Several examples for COLTRIMS data will be shown: double excitation and ionization of He as well as complete differential data in momentum space for many particle fragmentation of molecules by ions and photons. The obtained information on e-e correlation is discussed

[en] The subject of this paper is the K-shell excitation mechanism in energetic, nearly symmetrical heavy ion collision, investigated by particle-photon coincidence technique. The principle of the particle-photon coincidence technique is described elsewhere. A few improvements have been made. For particle detection, position sensitive detectors have been developed. The on-line data-taking system was constructed. The timing for proportional counters has been improved. The measured data are compared with the predicted (2p π - 2p sigma) - rotational coupling contribution. The increase at small b (kinematic peak) and a small hump at large b (adiabatic peak) have been found experimentally, however, the predicted valley between both peaks has not been observed. This is explained by the additional contribution of direct 2p sigma excitation. Peaks at large b were observed in the experiments of Cl ions on Ar and S ions on Ar, and were in good agreement with the theory. Experiment of the one-way vacancy transfer in the collision of Cl on Ti and Ni showed that for b smaller than the K-shell radius of a target, good agreement was obtained with the analytical calculation of Briggs. For heavier collision, the agreement was worse. The two-way vacancy transfer was investigated in the collision system of S¹⁵⁺ ions on Ar. Agreement with the prediction of Briggs was seen. (Kato, T.)
