The 63Cu and "0 nuclear spin-lattice relaxation rates in YBa$&Os have been measured in the temperature and magnetic field ranges of 1.4-270 K and 4.0-11 T, respectively. In the mixed state, 1 /T, for both 63Cu and "0 are enhanced by the magnetic field. Most strikingly, in a high field of 11 T, 63 (
NMR has been carded out in YBa2Cu4Oa with T~= 74 K. The nuclear quadrupole tensors in the oxygen sites were determined and compared with those in other h, igh-T~ cuprates. The hole densities in the oxygen and copper sites have been extracted from v~(O) and vQ(Cu) by assuming that the electric field
