Total Cross Sections for Interaction of 4.75 and 3.7 Bev/c K+ and π+ Mesons with Protons and Nuclei

Likhachev, M.F. ; Stavinskii, V.S. ; Y\"un-ch'ang, Hs\"u ; et al.

Sov.Phys.JETP 14 (1961) 29-31, 1962.

Inspire Record 1387792 DOI 10.17182/hepdata.70227

The total cross sections for interactions of K+ and 1r+ mesons with protons were measured. The following values were obtained: 21.3 ± 4.6 mb and 21 ± 4.3 mb for 4.75 ± 0.15 Bev/c and 3.7 ± 0.1 Bev/c K+ mesons, respectively; the corresponding values for 1r+ mesons of the same momenta were 33.3 ± 1.3mb and 30 ± 1.2mb. Data on the cross sections for inelastic collisions of K+ and 1r+ mesons with various nuclei have also been obtained.

Total reaction cross sections of 20 MeV π − and 30 MeV π + and π − have been measured for carbon and nickel targets. The experimental results are in very good agreement with calculations based on commonly accepted pion-nucleus potentials but disagree with calculations based on the potentials associated with the so-called pionic atom anomaly.
