General features of a detector setup for decay studies at on-line mass-separators are discussed. The detection system was used for measurements of S-decay properties of exotic nuclei with A approximate to 70. Results of GEANT Monte-Carlo simulations of the detector setup generally confirm the measurements. Both measurements and simulations show that even in case of low multiplicity events the Cc detector efficiency and peak to total ratio of gamma-lines are reduced by large factor due to summing. Steps to improve the detection system are discussed. (C) 1999 Elsevier Science B.V. All rights reserved.
