“…This is in contrast to results for p-p 9 and n-p 10 elastic scattering at the same incident momentum where the cross sections show smooth behavior and have a magnitude at large angles considerably greater than observed here.…”

NNcore interactions and differential cross sections from one gluon exchange

“…This is shown for a range of P~b in Fig. 3, adapted from Ryan et al [42], Ankenbrandt et aL [43], Clyde et al [44], Allaby et al [45], and from the ISR data of Nagy et at. [46] and Breakstone et al [47].…”

“…The data in the figure were obtained from the Durham-Rutherford HEP data archive. Near threshold the angular distribution is approximately isotropic, but as P~b increases the scattering at large angles falls rapidly, and at high energies the differential cross section is dominated by an asymptotic "diffractive peak, " expt bt = ae dt (41) lim s-+~, I~I/8&& For the purely hadronic part (as distinct from the divergent forward Coulomb peak) one finds and a' P' = 70 mb GeV (42) 6' p -11 -12 GeV (43) for the asymptotic form [47].…”

Large-Angle Proton-Proton Elastic Scattering at Intermediate Momenta

“…The fldaelal volume cuts used in the determination of the detection efficiency and in the final analysis steps werei (1) to discard all events in which the reconstruction Indicated the partlele woe not inside a 1" border around the active area ef the spark chambers, (11) to discord all events in which the reconstruction indicated that the F and/or S counters wore etrucV within i" or less ef the oountor edge and finally, (ill) to reject events for which the target support structure provided an aftlauthal cut.…”
