摘要：

The proton spin-lattice relaxation time T1 has been measured in a quasi one-dimensional S = 1 antiferromagnet NENP [Ni(C2H8N2)2NO2(ClO4)] between 1.3 and 50 K, and between 0.5 and 12 T. With increasing magnetic field or with increasing temperature T1 becomes short due to the breaking of the singlet-ground-state. At the critical field, B(c) = 9.8 T (B0//chain), T1 is extremely short suggesting a magnetic phase transition.
