An analysis of the electrical resistivity rho(T) of TmH/sub 2/ yields the spin-disorder resistivity rho/sub m/ and its temperature dependence. rho/sub m/ is constant at high temperatures (rho/sub m/ = 2.8 ..mu cap omega.. cm, a value which is much smaller than for pure Tm); at low temperatures, rho/sub m/(T) decreases and tends to zero. This result can be interpreted on the basis of a nonmagnetic ground state separated from the first excited state by a gap of 150/sup 0/K.
