Differential and partial cross sections of elastic and inelastic positronium-helium-atom scattering
Scattering of positronium (Ps) by helium atom has been investigated in a three-Ps-state coupled-channel model including Ps(1s,2s,2p) states using a recently proposed time-reversal-symmetric regularized electron-exchange model potential. Specifically, we report results of differential cross sections for elastic scattering and target-elastic Ps excitations. We also present results for total and d...
متن کاملTotal, elastic, and inelastic cross sections for positron and electron collisions with tetrahydrofuran.
We present total, elastic, and inelastic cross sections for positron and electron scattering from tetrahydrofuran (THF) in the energy range between 1 and 5000 eV. Total cross sections (TCS), positronium formation cross sections, the summed inelastic integral cross sections (ICS) for electronic excitations and direct ionization, as well as elastic differential cross sections (DCS) at selected in...
متن کاملDifferential cross sections for elastic and inelastic positronium-hydrogen-atom scattering
We report results of differential cross sections for elastic scattering, targetelastic Ps excitations and target-inelastic excitation of hydrogen in a five-state coupled-channel model allowing for Ps(1s)H(2s,2p) and Ps(2s,2p)H(1s) excitations using a recently proposed time-reversal-symmetric regularized electronexchange model potential. The present model yields a singlet Ps-H S-wave resonance a...
متن کاملThe 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...
