Observing Cross-Relaxation with Depth-Resolved 8Li β-NMR

In the paper, we review some of the progress that has been made, at the ISAC β-NMR facility, towards observing 8Li+ high field cross-relaxation phenomena in copper. The clearest observation of these phenomena is via the appearance of peaks in the field dependence of the relaxation rates of the 8Li+ polarization.
