摘要：

One of the possible microscopic models of nuclear spin relaxation 1/T1 and of the Knight shift K in YBa2CuO8 proposed is based on a strong electron-phonon interaction, which forms a carged Bose-liquid of small bipolarons (SB). An explanation of the large value of 63(1/T1), the absence of the Hebel-Slichter peak, the non-Korringa temperature dependence with the rapid decrease of 1/T1 and K above K above T(c) and a quantitative agreement with experiment is achieved.
