The binary and ternary fission of thorium, lead and platinum induced by 12.2 GeV protons

Abstract

In this work the binary and ternary fission of Th, Pb and Pt induced by 12.2 GeV protons has been analysed with a polycarbonate detector. The basic characteristics of the binary and ternary fission of the elements mentioned are given and corresponding values of the cross-sections are determined.

High energy fission cross sections induced by deuteron on 232Th and proton on natPb targets

“…The total fission cross section at 2 GeV protons on nat Pb estimated in the present work matches the experimental data of earlier publications [22,24,25]. Taken into account all available data on proton-induced fission on nat Pb presented up to today [22,[24][25][26][27][28] saturation can be accepted for total fission cross section at high energies. Therefore, we performed the same fitting process including the recent and our experimental results for nat Pb using equations 1 and 2.…”

“…The same conclusion arises from the 238 U saturation cross section (3.78 ± 0.38 b) which is 1.60 ± 0.16 times higher than the corresponding proton cross section. Similar ratios are observed comparing the fission cross section data available in the literature [8][9][10][24][25][26][27][28] for protons and deuterons at the same energy ranges. The deuteron fission cross section is 1.36 to 1.69 times higher than in the case of protons for energies around 100 MeV while for energies at the GeVs range the deuteron fission cross section is reduced, varying between 1.03 and 1.24 times the proton cross sections.…”
