Roy J. Holt Cadman, Robert Victor 2015-09-25T20:02:33Z 2015-09-25T20:02:33Z 10000-01-01 2001 2001 The spin observables Ay, iT 11, and Cy,y in proton-deuteron elastic scattering were measured over the angular range 65&deg; < theta cm < 115&deg; at a proton energy Tlab = 197 MeV. These data were acquired with a polarized proton beam and an internal vector-polarized deuteron gas target at the Indiana University Cyclotron Facility. The target was polarized by spin exchange with optically-pumped potassium; this experiment was the first to use this novel technique for polarizing hydrogen and deuterium. The data have been compared to existing Faddeev calculations using modern two-nucleon potentials which accurately reproduce the available two-nucleon scattering data. The calculations were also performed with the addition of the Tucson-Melbourne three-nucleon potential to identify kinematic regimes where the three-nucleon force makes a significant contribution. One such regime is in the vicinity of the minimum in the differential cross section for nucleon-deuteron elastic scattering at nucleon energies T lab &gsim; 100 MeV, which includes the region covered by this experiment. The failure of calculations using only two-nucleon potentials to reproduce the results of this experiment is interpreted as evidence that some type of three-nucleon force is needed to explain the data.
