We have measured the {sup 3}He(e,e{sup '}pp)n reaction at an incident energy of 4.7 GeV over a wide kinematic range. We identified spectator correlated pp and pn nucleon pairs by using kinematic cuts and measured their relative and total momentum distributions. This is the first measurement of the ratio of pp to pn pairs as a function of pair total momentum p{sub tot}. For pair relative momenta between 0.3 and 0.5 GeV/c, the ratio is very small at low p{sub tot} and rises to approximately 0.5 at large p{sub tot}. This shows the dominance of tensor over central correlations at this relative momentum.
