Improving treatment decision-making for patients with bipolar II disorder: Protocol for a phase II randomised controlled trial of a decision-aid website

Abstract

Solid ammonia (NH3) is commonly used as a dynamically polarized proton target for electron and muon scattering cross-section asymmetry measurements. As spin 1+ particles, the 14N nuclei in the target are also polarized and contribute a non-trivial asymmetry background that should be addressed. We describe here a method to extract the nitrogen contribution to the asymmetry, and report the cross-section asymmetries of electron–nitrogen scattering at beam energies of E=1.7 GeV and E=2.2 GeV, and momentum transfer of Q2=0.023−0.080 GeV2.
