　　We present and discuss NMR data obtained on high quality YbB6 single crystals.Both temperature-and field-dependent spin-lattice relaxation rate(1/T1)show a non-Fermi liquid behavior.Moreover,the values of 1/T1 at low temperature are several orders of magnitude larger than the expected value from itinerant electrons picture.
