Abstract
A previously introduced real-space renormalization-group treatment of the random transverse-held Ising spin chain is extended to provide det ailed information on the distribution of the energy gap and the end-to -end correlation function for long chains with free boundary condition s. Numerical data, using the mapping of the problem to free fermions, are found to be in good agreement with the analytic finite-size scalin g predictions. [S0163-1829(98)02737-4].
