The reasonableness of the continuous random network (CNR) model for the structure of tetrahedraUy coordinated amorphous semiconductors is demonstrated by Polk \[1 \], who showed that it is possible to connect rather rigid plastic and metal tetrahedral molecular units in a structure with little bond strain, no unsatisfied bonds and no perceptible long-range order \[1-3\]. For several years, our knowledge of the characteristics of these structures was based on laborious direct measurements of a single model of 440 units built by Polk \[1 \]. Models built by computer methods \[4, *Research supported in part by NSF. **Presenta ddress: Dept. of Physics, California Institute of Technology, Pasadena, California 91109.

N2 - Elastic-energy-relaxed 201-atom and 519-atom continuous-random-network structures are described, and G (r)'s, corrected for finite-size effects, are compared with experimental measurements on amorphous germanium. Excellent agreement is obtained for the principal peaks in G (r). Even subtle features of G (r) such as the shape of the second peak and structure between the second and third peaks accord remarkably well with experiment.
