The Froissart bound for inelastic cross-sections
We prove that while the total cross-section is bounded by (π/mπ) ln 2 s, where s is the square of the c.m. energy and mπ the mass of the pion, the total inelastic cross-section is bounded by (1/4)(π/mπ) ln 2 s, which is 4 times smaller. We discuss the implications of this result on the total cross-section itself. The Froissart bound [1], proved later from local massive field theory and unitarit...
متن کاملFroissart bound for inelastic cross sections
André Martin CERN, Theory Division, CH1211 Geneve 23, Switzerland (Received 19 May 2009; published 15 September 2009) We prove that while the total cross section is bounded by ð =m Þln2s, where s is the square of the c.m. energy and m the mass of the pion, the total inelastic cross section is bounded by ð1=4Þð =m Þln2s, which is 4 times smaller. We discuss the implications of this result on the...
متن کاملMeasurement of neutron inelastic scattering cross sections for 52Cr from threshold up to 18 MeV.
The powerful white neutron spectrum from Gelina is used for the investigation of gamma ray production cross sections in the reaction 52Cr(n,n'gamma)52Cr. The gamma rays from the inelastic process are detected with two large volume HPGe detectors placed at 110 degrees and 150 degrees with respect to the beam direction. The neutron flux has been measured with a 235U fission chamber. For the main ...
متن کاملMeasurement of elastic electron-neutron scattering and inelastic electron-deuteron scattering cross sections at high momentum transfer.
We have measured inelastic electron-deuteron, electron-proton, and electron-aluminum cross sections at 10' in the kinematic region between-elastic deuteron scattering and the second resonance region at six beam energies between 9.8 and 21 GeV. The elastic electron-neutron cross section was extracted from the quasi-elastic data at Q2 = 2.5, 4.0, 6.0, 8.0 and 10.0 (GeV/c)'. The ratio of elastic c...
متن کاملNeutron Cross Sections for Some Threshold Reactions
Three neutron reactions leading to production of the rare gases Ar41 and Xe135 have been in vestigated. Single crystal samples of KF, CaF2 , and BaF2 were irradiated in the Berlin reactor and the target-free absolute activities of the rare gas isotopes measured by a /^-/-coincidence method. The calculated cross sections are K41 (n,p)Ar41: o = ( 2 ,73±0,41) mb; o0= (98,6± 14,8) mb; Ca44(n,a)Ar4...
