摘要: The gamma-ray spectra emitted by decaying of residual nuclei produced spallation neutrons in (n, xn), xnyp), p), γ) reactions with activation threshold detectors, i.e. 209Bi, 197Au, 59Co, 115In, 232Th, were measured the Laboratory Nuclear Problems (LNP), JINR, Dubna, Russia. Spallation generated bombarding a 20 cm long cylindrical lead target 8 diameter surrounded 6 thick layer paraffin moderator 1 GeV proton beam from NUCLOTRON accelerator. Reaction rates and neutron spectrum compared CASCADE code calculations.
