O063000100014 FACILITY (SYNCH,4RUSITE) Medical Beam of the ITEP Synchrotron. O063000100015 SAMPLE Two targets of a nuclide under study, each about 500 O063000100016 mugramm/cm**2, were placed at 45 degree in respect to O063000100017 the proton beam direction. The targets of indium and O063000100018 antimony were prepared by vacuum evaporation onto an O063000100019 Aluminium backing, 150 mugramm/cm**2 thick. The O063000100020 Targets of silver and tin were self-supporting films. O063000100021 The targets were made of extra-pure materials. O063000100022 Presence of heavy fissile admixtures was checked by O063000100023 activation analysis and by thermal neutron irradiation.O063000100024 The admixture of uranium was found less than O063000100025 1*10**(-7) g/g in tin and less than 2.5*10**(-7) g/g O063000100026 in silver. O063000100027 METHOD (FISCT,EXTB,SITA). O063000100028 DETECTOR (GLASD) Silicate glass detectors, 0.5*1.7 cm**2 size, O063000100029 were placed around every target at 6 cm distance, O063000100030 covering 20-160 deg. angles with 10 deg. step. The O063000100031 detectors registered only particles with mass A>=20 O063000100032 and energy more than 13-15 MeV. O063000100033 Detection efficiency was calculated assuming a O063000100034 gaussian-shaped energy distribution of fission O063000100035 fragments in C.M.S., with the FWHM of 30 MeV.

O063000100045 The data were extrapolated up to 200 MeV by the authorsO063000100046 of the present work. No details of the extrapolation O063000100047 are available.

O063000100053 CORRECTION Performed: counting of fission fragments from O063000100054 the neighboring target, up to 11%; solid angle O063000100055 corrections; corrections to the fission fragment O063000100056 angular distribution taking into account the O063000100057 dependence of the detection efficiency on the fragment O063000100058 energy. O063000100059 Negligible: the contribution from the uranium O063000100060 admixture, not more than 1%. O063000100061 ERR-ANALYS (DATA-ERR) Complete analysis is not given.
