The deuteron D-state probability

Measurement of the differential cross-section and deuteron vector analyzing power in dp-elastic scattering at 2.0 GeV

“…The systematic error for A y due to accuracy of the beam polarization p y is estimated to be 13% [40].…”

“…The RF amplitudes for the corresponding hyperfine structure transitions were properly tuned to minimize the asymmetry in the vector polarization values for the both modes, as well as for the tensor polarization admixture, especially, for the mode (−2/3, 0) [39]. The evaluation of the vector polarization of the deuteron beam has been performed using the events from the reaction dp −→ ppn [40]. The deuteron beam polarization averaged over two polarization modes has been estimated as p y = 0.488 ± 0.061 by measuring the azimuthal asymmetry of quasi-elastic scattering using the known data on the analyzing powers for the elastic np-and ppscattering [41,42] The dp-elastic scattering events as a function of the scattering angle θ * .…”

“…Since in our case the tensor polarization is equal to zero [40] the differential cross-section can expressed as…”

“…Here p y is the vector polarization of the deuteron beam [40]. Since the false asymmetry effect of the A y value equals 1/(1 − p 2 0 ), it was neglected.…”
