  We present the first measurement of the angular distribution for the
exclusive process $\bar p p \to \psi(2S)\to e^+e^-$ based on a sample of 6844
events collected by the Fermilab E835 experiment. We find that the angular
distribution is well described by the expected functional form
$\frac{dN}{d\cos\theta^{*}}$ $\propto$ 1 + $\lambda \cos^{2}\theta^{*}$, where
$\theta^{*}$ is the angle between the antiproton and the electron in the center
of mass frame, with $\lambda$ = 0.67 $\pm$ 0.15 (stat.) $\pm$ 0.04 (sys.) The
measured value for $\lambda$ implies a small but non zero $\psi(2S)$ helicity 0
formation amplitude in $\bar p p$, comparable to what is observed in $J/\psi$
decays to baryon pairs.
