This thesis examines the effects of the hadronic spin flip amplitude in high energy elastic proton-proton collisions. In the first half the standard relativistic helicty formalism for particle interactions is built up. CMS, Laboratory, and Argonne lab scattering parameters for two measured spins are evaluated in terms of CMS and helicity amplitudes.
In the second half the influence of hadronic spin flip in the single transverse spin asymmetry, 
, is assesed. An analytic expression for the mean value of in the region of the maximum was derived and indicated hadronic dependences were not significantly reduced measuring over t ranges of the order of 
. In addition the same hadronic spin flip dependences were evaluated for the Quality value, 
. Maximizing this quantity reduces the statistical errors in the scattering count and so first order corrections to the bare CNI form of 
and are evaluated. In addition expressions were found for the mean value of the Quality over various t-ranges in the region of the
maximum.
I primarily thank my supervisor Dr. Nigel H. Buttimore who
gave generously of his time and whose guidance was invaluable.
I would also like to thank my team of helpers in room G29 for their combined efforts in processing this thesis, noteably Fabian Sievers for his help with Latex and Mathematica.
I also acknowledge the technical support of my collegues F. Callaghan and C. Reynolds.
