“…It can be noticed that for particles the ratio is approximately 4-5 times greater than for protons. Let us mention that our results are, within the experimental errors, close to those obtained with the same technique at lower incident energies of e particles [3,7], confirming the observation that binary cross sections do not change significantly for projectile energies greater than 1 GeV [2,3].…”

“…The errors are due to statistical and scanning errors, uncertainties in the thickness of the target layers and the errors in the integrated fluxes. The cross sections were corrected for systematic loss of events caused by the removal of the surface layer of the detector (2% of binary and 3% of ternary events) and by the coincidence of two events (0.1 of binary and 0.3% of ternary events [3] Our results show the same trend as proton data, but certain increase in magnitude, most probably due to geometrical reasons. However, there is a difference in the rate of the increase.…”

Makrofol was used as 4~ track detector to determine reaction cross sections of Ag, Au, Bi and Th induced by 8.8 GeV e particles. The variation of cross sections as functions of the Z2/A parameter of the target has been investigated. Data concerning geometry of events, momentum transfer and fission probabilities were discussed in order to discern fission products from those originating from more violent processes. Comparison with proton data has been done and differences were discussed.

“…In addition, the total fission cross section of nat Pb induced by 2 GeV protons was estimated by evaluating previous irradiation data. Cross section determination was achieved using fissionable targets, manufactured in the CNRS; Strasbourg, France, by evaporation on Lexan foils [22]. Lexan sheets were used also for the detection of fission fragments.…”

Total fission cross sections induced by deuterons with energies 1.6, 2.5 and 4.0 GeV on 232Th targets and by protons on natPb targets at energy 2.0 GeV were measured during irradiations at the Nuclotron accelerator, JINR, Dubna. Using Solid State Nuclear Track detectors, the fission cross sections induced by deuterons on 232Th were determined as 1277±216, 1232±207 and 1153±198 mb, corresponding to the energies mentioned above. The total fission cross section of protons on natPb was estimated by the same method as 131±30 mb. These results were compared to the previous systematic parameterization of proton induced fission and new values for the parameters of deuteron-induce fission on actinides, 232Th and 238U and proton induced fission on natPb were deduced. Fitting results obtained for deuterons on actinides are discussed and compared to results for protons.

“…This work has been complemented by a differential range and angular distribution study of certain isotopes by CRESPO et al [14] and detailed range measurements by PORILE and his coworkers [15,16]. Results on complex reactions occurring in the interaction of heavy target elements (U, Bi, Pb, Au, Ta) with high-energy protons have also been obtained with mica and plastic solidstate track detectors [17][18][19] and semiconductor counter systems [20,21]. The field has recently been reviewed [22][23][24][25], Some of the more essential experimental results, obtained by the numerous investigations so far, can be summarized as follows:…”

The ranges of radioactive iodine and bromine isotopes produced at 0.55 GeV and 18 GeV in uranium are determined. At 0.55 GeV the ranges of all isotopes are mass-independent, indicating that at this energy iodine and bromine isotopes are fission products. At 18 GeV, the ranges of neutron-deficient products decrease by a factor of two. A step-like range-vs.-isotopic mass is observed for iodine and also to some extent for bromine. The results of the range and yield measurements are qualitatively discussed in this paper. It is suggested to decompose the observed isotopic yield curves into a fission and deep spallation component. Some more quantitative calculations are presented in the consecutive paper. ZusammenfassungDie Reichweite radioaktiver Jod-und Bromisotope, die bei der Bestrahlung von Uran mit 0,55 und 18 GeV Protonen entstehen, wird bestimmt. Diese Reichweite ist bei 0,55 GeV massenunabhängig. Daraus wird geschlossen, daß bei dieser Energie alle Brom-und Jodisotope Spaltprodukte sind. Bei 18 GeV fällt die Reichweite neutronenarmer Isotope um den Faktor 2 ab. Eine stufenförmige Reichweite-vs.-Massenbeziehung wird für Jodisotope beobachtet; das gleiche gilt angenähert auch für Bromisotope. Die Ergebnisse der Reichweiten-und Ausbeutemessungen werden in dieser Arbeit qualitativ diskutiert. Es wird dabei vorgeschlagen, die beobachtete Isotopenausbeutekurve in eine Spaltprodukt-und "Tiefspallations"-Komponente zu zerlegen. Einige mehr quantitative Berechnungen werden in der folgenden Arbeit beschrieben.
