Vector analyzing poweriT11in theπd→2preaction between 112 and 325 MeV

The vector analyzing power $i{T}_{11}$ has been measured for the $\pi \mathrm{d}\to 2\mathrm{p}$ reaction at seven incident pion energies between 112 and 325 MeV, using a vector polarized deuteron target. The results cover an average of 12 angles per incident pion energy. A comparison with existing theoretical calculations is made. The value of these data with respect to ongoing phase shift analyses of the $\mathrm{pp}\to \pi \mathrm{d}$ reaction is discussed.
