Many total cross sections are rising

When experiments last year at the CERN Intersecting Storage Rings showed that the total cross sections for proton–proton collisions were rising about 10% as center‐of‐mass energies increased from 23 to 53 GeV, there was great excitement and considerable surprise. Now a tripartite team working at the Fermi National Accelerator Laboratory has investigated total cross sections from targets of protons and deuterons where the incident particles were protons, antiprotons, positive and negative kaons and positive and negative pions; incident energies ranged from 50 to 200 GeV in the laboratory system. By comparing the proton and deuteron cross sections, neutron cross sections were deduced.
