Abstract

Hydrogen. A number of workers have measured the absorption of hydrogen by tantalum ; thus Pirani1 found a large absorption at yellow heat, Moers2 measured the quantity taken up at higher temperatures, while Fetkenheuer3 found a maximum in the absorption at about 600° C. On the other hand, Sieverts showed a curve4 in which the quantity taken up Was greater at 20° C. than at higher temperatures. The clean-up at low pressures does not appear to have been discussed in detail, although Balke stated5 that below 1 micron the clean-up Was very small.
