Nous avons observé un changement brutal à 170 mK de la dépendance en température des temps de relaxation dans le D2 solide et nous interprétons ce changement par une transition de phase d'un verre quadrupolaire.We present new results for the nuclear spin-lattice relaxation times in solide n-D2(X(J=1)=0.33) at low temperatures. There is an abrupt change in the temperature dependance of the relaxation times at T ≈ 170 mK and we interpret this in terms of a possible transition to a quadrupolar glass phase
