M. Ferroluzzi et al., MEASUREMENT OF TENSOR ANALYZING POWERS FOR ELASTIC ELECTRON-SCATTERING FROM A POLARIZED H-2 TARGET INTERNAL TO A STORAGE-RING, Physical review letters, 77(13), 1996, pp. 2630-2633
We report an absolute measurement of the tensor analyzing powers T-20
and T-22 in elastic electron-deuteron scattering at a momentum transfe
r of 1.6 fm(-1). The novel approach of this measurement is the use of
a tensor polarized H-2 target internal to an electron storage ring, wi
th in situ measurement of the polarization of the target gas. Scattere
d electrons and recoil deuterons were detected in coincidence with two
large acceptance nonmagnetic detectors. The techniques demonstrated h
ave broad applicability to further measurements of spin-dependent elec
tron scattering.
