A measurement of cross sections for 208Pb from threshold up to 20 MeV

Neutron activation cross sections on lead isotopes

“…The incident deuteron energies were 1, 2, 3, and 4 MeV. Neutrons with energy 3.45 MeV were produced by a 4.3 MeV proton beam on a solid-state Ti/T target via the 3 H(p,n) 3 He reaction (Q = −0.764 MeV). The typical beam current was 10 µA.…”

“…For 208 Pb the same modifications as those used in Ref. [3] were employed for the neutron optical model as these improve the description of scattering data [3,44]. The level density model is a combination of the constant temperature approach at low energy and the back-shifted Fermi-gas model with energy dependent level density parameters according to Ignatyuk's proposal.…”

“…In this respect, isomer cross sections are very similar to (n,xnγ ) cross sections obtained for states that decay with much shorter half-lives. Related earlier work of the present authors includes the study of such (n,xnγ ) cross sections for lead isotopes and bismuth and the population of isomers of Au and Hg through different reaction channels [2][3][4][5].…”

Detailed Analysis of Differential Cross Sections of Elastic Scattering for n+208Pb Reaction

“…These parameters, therefore, have become important theoretical and experimental data. Accurate nuclear data are needed for the design of a new generation of nuclear power reactors, that aim at a sustainable fuel cycle or are dedicated to the elimination of high level long-lived radioactive waste [4].…”

“…It was intensively studied in the past due to its double magic nuclear structure [4] and it is one of the important materials considered for the design of a new generation of nuclear reactors. The neutron radius of a heavy nucleus such as 208 Pb is a fundamental nuclear structure quantity that remains elusive [5].…”
