Impressive bounds on the magnitude of spin dependent hadronic amplitudes have been obtained from values of the analyzing power and asymmetries provided by studies of low angle proton elastic scattering at the Relativistic Heavy Ion Collider. A bound on the single flip amplitude does rely upon knowing other amplitudes sufficiently accurately, particularly their phases, including the Coulomb phase. An examination of the maximum of the asymmetry AN suggests evaluating the important helicity dependent hadronic amplitudes through further measurememts of spin observables in the low momentum transfer region at a number of energies and over a range of nuclei of different spins. The possible use of the dynamics of storage rings in this endeavour is outlined. © 2007 American Institute of Physics [ABSTRACT FROM AUTHOR]
