Summary

THE ELECTRON DIFFRACTION STUDIES ARE CARRIED OUT ON INDIUM FILMS DEPOSITED IN HYDROGEN ATMOSPHERE ON A SUBSTRATE COOLED BY LIQUID HELIUM DOWN TO ABOUT 3.5 OR 4.5 K. THE MEASUREMENTS OF INTERPLANE DISTANCES MAKE IT POSSIBLE TO CALCULATE HYDROGEN CONCENTRATION IN CRYSTALLITES. THE DISSOLVED HYDROGEN IS FOUND TO PRODUCE A REDUCTION IN TETRAGONAL DISTORTION OF INDIUM LATTICE TILL IT BECOMES COMPLETELY CUBIC. THE ORIGINAL STATE OF PHASE IS FOUND TO BE LABILE, AND AN INITIAL STAGE OF THE STATE DECAY IS OF SPINODAL NATURE. BOTH HOMOGENEOUS COMPRESSION OF THE WHOLE FILM AND THE APPEARANCE OF INHOMOGENEOUS MICROSTRESSES BALANCED WITH SEPARATE CRYSTALLITES ARE OBSERVED. THE DATA INDICATE THAT AT A TEMPERATURE LOWER THAN 5 K THE MOBILITY OF HYDROGEN IN INDIUM FILMS IS VERY HIGH.
