Abstract

We report, for magnetic fields of 0, 8.8, and 14.8 T, measurements of the temperature dependent $^{63} Cu$ NMR spin lattice relaxation rate for near optimally doped ${YBa}_{2} {Cu}_{3} O_{7 - δ}$ , near and above $T_{c}$ . In sharp contrast with previous work we find no magnetic field dependence. We discuss experimental issues arising in measurements of this required precision and implications of the experiment regarding issues including the spin gap or pseudogap.
