Cross sections for the (n, n') and (n, 2n) reactions on 113In and 204Pb

Neutron activation cross sections on lead isotopes

“…At higher energies the present work is in good agreement with most of the results obtained at 14 MeV [61][62][63]65,75,76]. Above 14 MeV the only other result is by Decowski et al [77]. The latter work agrees rather well with the present results but appears to be systematically somewhat low with regard to most of the data.…”

“…Above 18 MeV the results are unique and above 16 MeV the only other data are those of Decowski et al [77] which have a much larger uncertainty and a peculiar shape around 14 MeV. Together with the results of Hanlin et al [78] and the average of the results around 14 MeV [61][62][63]65,70,76,[79][80][81][82] our data establish an excitation curve for this reaction from threshold to 20 MeV.…”

A consistent study of precompound and compound-nucleus emission mechanisms in neutron-induced reactions

“…It was observed that, depending on the excitation energy and mass of the nuclei, the precompound mechanism may even become the dominant process in the emission of primary neutrons [1][2][3][4][5], protons [1,[5][6][7] and alpha particles [1,5,[8][9][10][11][12][13]. In reactions leading to the emission of more than one particle, such as (n, pn), (n, rip), (n, 2n), (n, 3n), etc., the mechanism of sequential emission of particles may not necessarily be identical for all particles involved.…”
