M039000100014 FACILITY (ESTRG,4RUSSIB) ROKK-1M facility of BIMP, Novosibirsk. M039000100015 SAMPLE Metalic foils of the target elements. all target M039000100016 materials are of natural isotopic composition. M039000100017 METHOD (EXTB,SITA) M039000100018 DETECTOR (TRD) MACROFOL fission-track-etch detectors. M039000100019 ANALYSIS The direct fission fragment track counting. M039000100020 CORRECTION To obtain the final values of the physical quantities M039000100021 and associated errors, the data have been treated by M039000100022 considering the statistics and efficiency of track M039000100023 counting (was estimated to be about 72 - 86 %). The M039000100024 appropriate corrections for both gamma-beam M039000100025 attenuation through the stacks and self-absorption M039000100026 of fission fragments by the target materials for M039000100027 thinand thick-target geometry. M039000100028 ERR-ANALYS (ERR-T) The total - statistical plus systematic - M039000100029 errors are given. M039000100030 (ERR-SYS) Systematic errors. M039000100031 COMMENT Photofission cross sections of Bi-209, Pb-nat, M039000100032 Au-197, Pt-nat, W-nat, Ta-181, V-51, and Ti-nat M039000100033 nuclei have been measured at the incident photon M039000100034 energy of 100 MeV using monochromatic photons M039000100035 produced by compton backscattering at the ROKK-1M M039000100036 facility in BIMP, Novosibirsk. Detection of fission M039000100037 fragments has been performed by means of MACROFOL M039000100038 track-etch detectors in close contact with metalic M039000100039 foils of the target elements. The values of M039000100040 fissility at 100 MeV deduced for the targets under M039000100041 investigation are found to range between 10**-4 and M039000100042 10**-2. The present results show consistency with M039000100043 the fissility trends calculated for 69 and 600 MeV M039000100044 monoenergetic photons using a formalism based on the M039000100045 current two-step model for intermediate-energy M039000100046 photofission reactions.
