Spin observables and reconstruction of π-d elastic scattering amplitudes in transverse frame

Abstract

The authors show that the measurement of only eight real parameters consisting of the differential cross section y0, the analysing power T20 and the polarisation transfer observables Cx,x, Cx,y, Cy,y, Cx,xz, Cx,yz and Cy,xz are sufficient for the complete determination of pi -d elastic scattering amplitudes in the transverse frame.
