SAMPLE     Enriched 204PbS targets (0.5 mg/cm2 thick) on a        F151200100014

DETECTOR   (SISD) GABRIELA detector array was used to detect the  F151200100020 
           residues and their subsequent alpha decay or fission   F151200100021 
           as well as gamma rays, X rays and conversion           F151200100022 
           electrons. The evaporation residues pass through a     F151200100023 
           time of flight detector and are then implanted into a  F151200100024 
           10x10 cm2 500 mu-m thick double-sided silicon strip    F151200100025 
           detector. Particles escaping from the DSSD are         F151200100026 
           detected in eight 6x5 cm2 DSSDs with 16 strips on each F151200100027 
           side.                                                  F151200100028 
           (GE)The Ge array consists of a large clover detector   F151200100029 
           installed just behind the DSSD and 4 coaxial detectors F151200100030 
           forming a cross around the DSSD.                       F151200100031 
METHOD     (OLMS) The separator for heavy elements spectroscopy   F151200100032 
            (SHELS) was used to select the evaporation residues.  F151200100033

ADD-RES    (DECAY) Two fission activities with half-lives of      F151200100035 
           52.8(4.4) mu-sec and 9.9(1.2) ms were measured for     F151200100036 
           253Rf. A third state, at much higher excitation        F151200100037 
           energy, was also observed 0.66 (+0.40/-0.18) ms.       F151200100038
