Summary

THE GOLD-0.03 AT% IRON/CHROMEL P THERMOCOUPLE WAS CALIBRATED BETWEEN 1 AND 300 K TO MONITOR THE TEMPERATURE OF FREELY VIBRATING SPECIMENS IN MEASUREMENTS OF ELASTIC ENERGY DISSIPATION. IN THE INTERMEDIATE TEMPERATURE RANGE (50-23 K) THE CALIBRATION POINTS WERE OBTAINED BY MEANS OF A MINIATURE SEALED CELL CONTAINING OXYGEN, WHICH GAVE THREE FIXED POINTS: THE O2 TRIPLE POINT, 54.3610 K ; THE BETA-GAMMA TRANSITION, 43.803 K ; AND THE ALPHA-BETA TRANSITION, 23.873 K.
