O060500100021 METHOD (EXTB,STTA,FISCT,COINC,ACTIV,MOSEP) Correlated O060500100022 fission fragment tracks were observed after the O060500100023 chemical treatment of the detectors. O060500100024 SAMPLE The layers of natural uranium of about 5 ug/cm2 O060500100025 were obtained by electrospraying or by thermal O060500100026 evaporation of uranium tetrafluoride. O060500100027 The layers of bismuth, natural lead, gold, natural O060500100028 tellurium, natural tin and natural silver of about O060500100029 20-100 ug/cm2 were obtained by thermal evaporation O060500100030 of metals.

O060500100049 COMMENT -By authors- For the determinations of cross section O060500100050 for binary fission, the following scanning criteria O060500100051 were adopted for correlated pairs of tracks: O060500100052 - the track ranges exceeded 3 um; O060500100053 - the distance between the fragment entry points O060500100054 were less than about 20 um.
