Original Abstract

For the design and modeling of Accelerator Driven sub-critical System (ADS) a detailed study of response of ADS materials to the spallation neutrons is required. For this purpose reaction rates of different reactions like (n, xn) and (n, xnyp) in Bi-209, Mo-nat, Fe-56, Ni-nat, Mn-55, Ti-nat and Co-nat materials are determined in an experiment conducted at Nuclotron of JINR, Dubna, using 1.6 GeV d-beam in the 'Energy + Transmutation' set-up. Reaction rates of various (n, xn) and (n, xnyp) reactions are studied in these samples. Results of reaction rates deduced from all the gamma peaks observed in case of Bi-209 (n, xn) reactions with x=3-9, Mo-nat (n, gamma), (n, 3n), (n, 6n), Fe-56 (n, p), (n, p2n), (n, p4n), Ni-nat (n, 2n), (n, 3n), (n, p), (n, d), (n, t), Mn-55 (n, gamma), (n, 2n), (n, 4n), Ti-nat (n, p), (n, d), (n, t) and Co-nat (n, 7), (n, xn) reactions with x=2-5 along with (n, p), (n, 2p2n), (n, 2p4n) and (n, 2p6n) are presented. The measured reaction rates for all the elements show good consistency for all the reaction channels and all observed E's of the product nucleus. For all the above mentioned reactions, both experimental as well as theoretical spectrum average cross-sections (sigma(sp,av,cs)) are deduced and compared. A close agreement is found between the experimental sigma(sp,av,cs) and theoretical sigma(sp,av,cs) values.
