Summary

A SPECIAL CALORIMETER IS DESCRIBED WHICH IS CAPABLE OF DETECTING MOLECULAR HYDROGEN TRAPPED IN SOLID MATERIAL. IT TAKES ADVANTAGE OF THE ENERGY RELEASED BY THE SLOW ORTHO-PARA CONVERSION OF H2 AFTER RAPID COOLING TO 4.2 K. THE TECHNIQUE IS SIMPLE, QUANTITATIVE, AND NONDESTRUCTIVE, AND CAN BE USED ON ANY NONMAGNETIC HOST WITH A SENSITIVITY OF ABOUT 1 PPM FOR A 1-CM3 SAMPLE. THE RATE OF DECAY ALSO GIVES INFORMATION ABOUT THE LOCAL CONFIGURATION OF THE H2.
