“…6. We compared our results with earlier data of Smirnov et al [17] (based on the previous work of Eismont et al [22]) as well as with the experimental data from Prokofiev [23]. These data agree well with ours within their measured energy ranges (up to 200 MeV).…”

Neutron-induced fission cross sections for nat Pb and 209 Bi were measured with a white-spectrum neutron source at the CERN Neutron Time-of-Flight (n TOF) facility. The experiment, using neutrons from threshold up to 1 GeV, provides the first results for these nuclei above 200 MeV. The cross sections were measured relative to 235 U and 238 U in a dedicated fission chamber with parallel plate avalanche counter detectors. Results are compared with previous experimental data. Upgraded parametrizations of the cross sections are presented, from threshold energy up to 1 GeV. The proposed new sets of fitting parameters improve former results along the whole energy range.

Analysis of the main nuclear-physical characteristics of the interaction of proton beams with heavy metal targets

It is shown that the concept of relativistic heavy-nuclear energy is untenable. Using a large group of different experiments in the proton energy range 0. it is demonstrated that the high-energy hadron transport program SHIELD, which is based on modern nuclear models, has predictive power. The interaction of protons with energy ranging from 0.1 to 100 GeV with a simple model system target + blanket, containing heavy elements (lead, thorium, depleted and enriched uranium), is examined. The energy release, neutron production, and production of fissile isotopes in the system are calculated. It is found that for all values of the proton energy which are considered the useful yield of energy in weakly fissile media is inadequate (thorium, depleted uranium) and is completely absent in non-fissile media (lead). A blanket containing enriched uranium will be necessary in order to use the scheme for useful production of energy. In this variant, the optimal proton energy is 1-3 GeV, which corresponds to the conventional concept of electronuclear facilities whose main purpose is to transmute nuclear wastes and produce electricity at the same time.The concept of commercial production of energy using accelerators to accelerate heavy charged particles has been discussed since the beginning of the 1950s. According to this concept, a beam of protons or ions with sufficiently high energy should generate a large number of neutrons on interacting with a heavy target. Facilities which function according to this principle are said to be electronuclear facilities. The accelerator must be a high-current accelerator in order to produce more neutrons, and for this reason the target is a complicated technical system. An advantage of electronuclear facilities over conventional nuclear reactors is that there is no possibility of reactivity accidents.

“…Lisowski et al [10] and Shcherbakov et al [12] measured the fission cross-section data from a spallation source in a wide energy range up to about 200 MeV. Also, there are the results of Goldanskiy et al [8] at 120 and 380 MeV, Eismont et al [11] at 135 and 162 MeV, and those of Pankratov et al [9] covering the range from 5 to 37 MeV, with 5 points above 30 MeV.…”
