Abstract
Using the Crystal Barrel(CB)/TAPS detector system at the ELSA accelerator facility in Bonn the η' photoproduction off nuclei (C, Ca, Nb and Pb) was studied via the hadronic decay channel η' -> Ï^0Ï^0η. Recent results on the in-medium properties of the η'-meson, derived from the transparency ratio measurements, are presented. The absorption of the η'-meson in nuclear matter is compared to the properties of other mesons (η, Ï).
