Cross Section and Tensor Analysing Power of the $\vec{d}d\to \eta \alpha$ Reaction Near Threshold

The GEM Collaboration, A. Budzanowski, A. Chatterjee +29

The angular distributions of the unpolarised differential cross section and tensor analysing power $A_{xx}$ of the $\vec{d}d\to \alpha \eta$ reaction have been measured at an excess energy o…
