dc.description.abstract	The magnetic nuclear spin-lattice relaxation has been studied in PrF3. It was found that 141Pr spin-lattice relaxation rate is untypically high for the Van Vleck insulator. According to all existing experimental data the only relaxation channel for enhanced nuclear moments at low temperatures is interaction with paramagnetic impurities and typical nuclear relaxation rate in rare earth Van Vleck paramagnets at liquid helium temperatures is 1s−1. The measured value is 100s−1. At the assumption that relaxation is caused by the strong4f-4fcooperative interaction mediated by phonons [1], we measured 141Pr relaxation rates in a number of PrxLa1−xF3 samples and foundthat in diluted samples relaxation slows down to the usual for insulators values	ru_RU
