DETECTOR   (SISD) GABRIELA detector array was used to detect the  F1512001   20 
           residues and their subsequent alpha decay or fission   F1512001   21 
           as well as gamma rays, X rays and conversion           F1512001   22 
           electrons. The evaporation residues pass through a     F1512001   23 
           time of flight detector and are then implanted into a  F1512001   24 
           10x10 cm2 500 mu-m thick double-sided silicon strip    F1512001   25 
           detector. Particles escaping from the DSSD are         F1512001   26 
           detected in eight 6x5 cm2 DSSDs with 16 strips on each F1512001   27 
           side.                                                  F1512001   28 
           (GE)The Ge array consists of a large clover detector   F1512001   29 
           installed just behind the DSSD and 4 coaxial detectors F1512001   30 
           forming a cross around the DSSD.                       F1512001   31 
METHOD     (OLMS) The separator for heavy elements spectroscopy   F1512001   32 
            (SHELS) was used to select the evaporation residues.  F1512001   33

ADD-RES    (DECAY) Two fission activities with half-lives of      F1512001   35 
           52.8(4.4) mu-sec and 9.9(1.2) ms were measured for     F1512001   36 
           253Rf. A third state, at much higher excitation        F1512001   37 
           energy, was also observed 0.66 (+0.40/-0.18) ms.       F1512001   38
