Experimental study of the A(e,e 'pi(+)) reaction on H-1, H-2, C-12, Al-27, Cu-63, and Au-197

Qian, Xin; Dutta, D.; Gao, Haiyan; Kramer, K. (AMER PHYSICAL SOC, 2010)

Cross sections for the H-1(e,e'pi(+))n process on H-1, H-2, C-12, Al-27, Cu-63, and Au-197 targets were measured at the Thomas Jefferson National Accelerator Facility ( Jefferson Lab) to extract nuclear transparencies. ...
Polarization Transfer in the He-4((e)over-right-arrow, e '(p)over-right-arrow)H-3 Reaction at Q(2)=0.8 and 1.3 (GeV/c)(2)

Qian, Xin (AMER PHYSICAL SOC, 2010)

Proton recoil polarization was measured in the quasielastic He-4((e) over right arrow, e '(p) over right arrow)H-3 reaction at Q(2) = 0.8 and 1.3 (GeV/c)(2) with unprecedented precision. The polarization-transfer coefficients ...
Scaling of the F-2 Structure Function in Nuclei and Quark Distributions at x > 1

Dutta, D.; Qian, Xin (AMER PHYSICAL SOC, 2010)

We present new data on electron scattering from a range of nuclei taken in Hall C at Jefferson Lab. For heavy nuclei, we observe a rapid falloff in the cross section for x > 1, which is sensitive to short-range contributions ...
