Opis:: The installation of the wavelength shifter at the BESSY I storage ring in Berlin makes it possible to apply the synchrotron radiation for white beam investigations of organic multilayers. Considering the energy characteristic of the synchroton radiation source and the absorbance of the beryllium window the synchrotron radiation can be used outside the UHV system for X-ray reflectometry and X-ray diffuse scattering between about 3 keV and 25 keV. Between 3 and 10 keV the synchrotron radiation intensity is high enough to realize the grazing incidence diffraction mode in order to get in-plane information. The capability of the methods is demonstrated at the example of a Pb-stearate multilayer covered by a thin polyelectrolytic polymer layer.

Opis:: Negative-charged ion energy spectra of the Fe$\text{}_{3}$O$\text{}_{4}$ (001) and (111) surface revealed large peaks attributed to the O$\text{}^{-}$ recoils from a binary collision. Under Ar$\text{}^{+}$ ion bombardments such an emission was largely affected by the screening effect of the Fe ions. A distinguished peak related to the O$\text{}^{+}$ recoil ions was observed under Ne$\text{}^{+}$ ion bombardments, while such a peak was merged into the high background in the case of Ar$\text{}^{+}$ ion ones. A weak effect from the Verwey transition was found on oxygen emissions. For the (111) surface a small peak characteristic of the O$\text{}^{+}$ recoils from double collisions appeared in the energy spectra around 140-170 K and a minimum was observed in both R$\text{}^{+}$(T) and R$\text{}^{-}$(T) curves under 6 keV Ne$\text{}^{+}$ ion beam.
