“…Moreover, previous measurements give the same result for the corresponding energy range [4,35,12]. Early neutron reaction cross sections measured at GeV [36][37][38][39][40] show the same values and can be compared with recent measurements, taking into account that cross sections above 1 GeV have no significant variation.…”

The inelastic cross section of deuterons hitting a Lead target has been determined by the beam attenuation technique. A spallation neutron source based on Lead target has been irradiated with 1.6 and 2.5 GeV deuterons. Solid state nuclear track detectors as well as the activation method were used in order to obtain the neutron and proton distribution along the surface of the source. The attenuation coefficient was estimated by fitting the experimental data taking into account the build up effect and the beam attenuation. Using the attenuation coefficient, the interaction length and then the inelastic cross section of deuterons on Lead reaction have been determined.

“…I n the early work (see, for example, Atkinson et al 1961) neutrons were identified by detecting, in a gas Cherenkov counter, the pions produced in nuclear interactions by the neutrons entering a beryllium absorber. T h e threshold setting of the Cherenkov counter determined the mean energy of the neutrons (about 5 Gev), and defined it with an accuracy to about kO.5 Gev.…”

“…Several experiments have been done to determine a,(np) directly, by measuring the attenuation of a neutron beam in liquid hydrogen, in good-geometry experiments (Atkinson et al 1961, Ozhdyani et al 1962, Khachaturyan and Pantuyev 1964, Palevsky et al 1964). More recently, experiments of higher statistical accuracy have been carried out for both hydrogen and deuterium (Kreisler et al 1966, Engler et al 1968) and these new data, together with the earlier work, are shown in figure 17(a) and (b).…”

Neutron-nucleus total cross sections at 5.7 GeV/c

et al. 1970

The neutron total cross sections for He, Be, C, A1, Fe, Cu, Cd, W, Pb and U have been measured to an accuracy of 2 % at 5.7 ± 0.6 GeV/c. The total cross section versus atomic weight data was fit to an absorbing uniform grey sphere optical model. The best fit parameters are R = aoA1/3 where a o = 1.27 =e0.01 fm, and a nucleon mean free path in nuclear matter of 3.0 ±0.2 fm. The energy dependence of the nucleonnucleus total cross sections is discussed in terms of the nucleon-nucleon total cross sections and a screening term.
