Abstract
Finite-size scaling methods are used to study the critical behavior of the quantum one-dimensional random Ising model in a transverse field. Estimates of the critical coupling are exhibited for several values o f the probability p characterizing the double-delta distribution of th e exchange interaction. They are in good agreement with exact results of Pfeuty [ Phys. Lett. A 72 (1979) 245).
