Аннотация
The temperature dependences of the electrical resistivity of thin (d = 100−1000 Å) cold-deposited sodium films have been investigated. Anomalies were found in the R(T) relation for films of thickness d < 750 Å in the temperature range up to 100 °K. Comparison of the anomalies in R(T) with results of structural investigations enabled a qualitative model to be constructed of the structural transformation processes which take place on annealing cold-deposited Na films.
