Summary

UNSTEADY CREEP OF NORMAL HYDROGEN (75% ORTHOHYDROGEN) IS STUDIED IN THE WIDE TEMPERATURE RANGE 1.8 TO 12 K AND THAT OF PARAHYDROGEN WITH REDUCED TO 0.2% ORTHOCONTENTS AT HELIUM TEMPERATURES. DEPENDING ON THE TEST TEMPERATURE OR THE DEUTERIUM IMPURITY CONTENTS IN THE SAMPLES, THE SOLID HYDROGEN DEFORMATION IS SHOWN TO OBEY TWO DIFFERENT TIME LAWS. IN THE REGION OF HELIUM TEMPERATURES, WHERE THE CREEP N-H2 IS LOGARITHMIC, IT SHOWS NO DEPENDENCE ON TEMPERATURE. CREEP IN PURE PARAHYDROGEN IS DUE TO DISLOCATION CLIMB AT TEMPERATURES DOWN TO 1.8 K. THE IMPORTANCE OF QUANTUM EFFECTS IS DISCUSSED.
