COMMENT    -By authors. As was considered to be useful to         O053300500004 
           investigate the influence of secondary particle on the O053300500005 
           production of bromine fission products from uranium at O053300500006 
            18-GeV at CERN-PS, since the cross section for bromineO053300500007 
           isotopes are measured here. Therefore, relative        O053300500008 
           isotopic yields for bromine were determined in a thin  O053300500009 
           target-22 mg/cm**2 and a normally used thick target    O053300500010 
            133-mg/cm**2. The thin target consisted of two 40-mum O053300500011 
           Al-foils and 500-mugr uf between them. Two experiments O053300500012 
           were carried out with thin targets.                    O053300500013 
           The ratios of relative isotopic yields in thin and     O053300500014 
           thick targets have been normalized to Br-80 as being   O053300500015 
            1.0.                                                  O053300500016
