摘要：

Precise measurements of the single spin asymmetry, AN and the double spin asymmetry, ANN, in proton-proton (pp) elastic scattering in the region of four-momentum transfer squared 0.001 < -t < 0.032 (GeV/C)(2) have been performed using a polarized atomic hydrogen gas jet target and the RHIC polarized proton beam at 24 GcV/c and 100 GeV/c. The polarized gaseous proton target allowed us to achieve the measurement of A(NN) in the CNI region for the first time. Our results of AN and ANN provide significant constraints to determine the magnitude of poorly known hadronic single and double spin-flip amplitudes at this energy.
