Abstract

In the framework of the ALPOM II experiment, we compare the figure of Merit of two processes for the neutron analyzing power measurement in the reactions $\vec n + p \to \vec n + p$ and $\vec n + p \to p + \vec n$ in the beam momentum range from 1 to 6 GeV. Based on a pole model calculation for the cross sections and existing data for analyzing powers, this study suggests that for neutron momentum larger than 3 GeV, the process of $\vec n + p \to p + \vec n$ is more effective for polarimetry.
