A quasi-liquid layer existing at the interface between the glass tube and the ice specimen served as a high speed path for the tritium diffusion. The experimental setup was focused to estimate the diffusion coefficient of tritium in a quasi-liquid layer at the interface. Preliminary results of the laboratory measurements conducted show that a quasi-liquid layer does exist, serving as a high speed diffusion path and that the diffusion coefficient is estimated to range from 10-13 to 10-12 m2/s at -0.8℃. Furthermore, separate experimental investigations are planned to obtain the numerical values of the diffusion coefficient and the layer thickness., Article}, pages = {97--102}, title = {固体と氷界面研究へのトリチウムの応用}, volume = {7}, year = {1987} }
