The NQR spectra and the nuclear spin-lattice relaxation rate 1/T~ associated with the Cu(2) sites in Y~ -~Pr~BazCu307 with x = 0.1 and 0.2 have been investigated. The spectrum of Yo.sPro.2Ba2Cu30~ at 4.2 K is found to be broadened in the high-frequency side, and the half-width becomes two times of t
