Four new active galaxies with steep soft X-ray spectra
J. Greiner, R. Danner, N. Bade +3
We have discovered four AGN in the ROSAT all-sky-survey data with very steep X-ray spectra. We apply several models to these X-ray spectra with emphasis on warm absorber models whi…

Spin effects in hard exclusive reactions
P. Kroll
The present status of applications of perturbative QCD to large momentum transfer exclusive reactions is discussed. It is argued that in the region of momentum transfer accessible…

THE LARGE MOMENTUM TRANSFER BEHAVIOUR OF MESON-PHOTON TRANSITION FORM FACTORS
P. Kroll
It is reported on predictions for the - transition form factor obtained within a perturbative approach which includes transverse momentum effects and Sudakov corrections. The…
