We have measured the total cross-section difference for pp scattering in initial spin states parallel to the beam direction at beam momenta of 1.17, 1.47, 1.69, 1.97 and 2.49 GeV/ c . This measurement was done in a standard transmission experiment. A striking energy dependence is observed with a maximum difference of −16.9 mb at P lab = 1.47 GeV/ c .

Measurement of the Transverse Spin Dependence of the p p Total Cross-Section in the 1-GeV/c-3-GeV/c Region

Biegert, E.K. ; Buchanan, J.A. ; Clement, J.M. ; et al.
Phys.Lett.B 73 (1978) 235-238, 1978.
Inspire Record 134224 DOI 10.17182/hepdata.27471

The pp total cross section difference between pure transverse spin states was measured in the laboratory momentum range 1–3 GeV/ c . Significant differences were found and these differences show striking energy dependence. This structure is in disagreement with the predictions of simple exchange models.
