COMMENT -By author. "Partially cumulative" yields are given O053300200005
when in dependent and cumulative yields can only be O053300200006
determined with rather large uncertainties, but the O053300200007
result for a constant ratio of independent-to- O053300200008
cumulative (I.E. Parttially cumulative) yield is O053300200009
considerably more accurate. O053300200010
-By author. Our results is shown that cross section O053300200011
increased by (20 +/- 5%) for 119-123-I between 550 MeV O053300200012
and 590 MeV. This effect is surprisingly large. O053300200013

COMMENT -By authors. As was considered to be useful to O053300400004
investigate the influence of secondary particle on the O053300400005
production of bromine fission products from uranium at O053300400006
18-GeV at CERN-PS, since the cross section for bromineO053300400007
isotopes are measured here. Therefore, relative O053300400008
isotopic yields for bromine were determined in a thin O053300400009
target-22 mg/cm**2 and a normally used thick target O053300400010
133-mg/cm**2. The thin target consisted of two 40-mum O053300400011
Al-foils and 500-mugr uf between them. Two experiments O053300400012
were carried out with thin targets. O053300400013
The ratios of relative isotopic yields in thin and O053300400014
thick targets have been normalized to Br-80 as being O053300400015
