【 摘 要 】
A beam of 1 GeV proton coming from Dubna Nuclotron colliding with a lead target surrounded by 6 cm paraffin produces spallation neutrons. A Th-foil was kept on lead target (neutron spallation source) in a direct stream of neutrons for activation and other samples of 197Au, 209Bi, 59Co, 115In and 181Ta were irradiated by moderated beam of neutrons passing through 6 cm paraffin moderator. The gamma spectra of irradiated samples were analyzed using gamma spectrometry and DEIMOS software to measure the neutron cross-section. For this purpose neutron fluence at the positions of samples is also estimated using PREPRO software. The results of cross-sections for reactions 232Th(ð‘›, ð›¾), 232Th(ð‘›, 2ð‘›), 197Au(ð‘›, ð›¾), 197Au(ð‘›, ð›¼), 197Au(ð‘›, ð‘¥ð‘›), 59Co(ð‘›, ð›¼), 59Co(ð‘›, ð‘¥ð‘›), 181Ta(ð‘›, ð›¾) and 181Ta(ð‘›, ð‘¥ð‘›) are given in this paper. Neutronics validation of the Dubna Cascade Code is also done using cross-section data by other experiments.
