    Notes: Abstract A thin Bi layer is irradiated by X-rays so thatL-Auger electrons are emitted. A magnetic lens spectrometer is used to measure the electron spectrum. Energy, transition, and relativ intensity are given for 14 lines. Under the most favourable conditions the number ofL III ionisations is about ten times that ofL II ionisations. In this case only a small intensity ofL II-Auger electrons is superposed on theL III-Auger spectrum. The ratiod of intensities of line groupL III M N to line groupL III M M is found by extrapolation to bed=0·46±0·02. This combined with earlier results gives anL III-Auger yielda 3= 0·64±0·04. TheL III fluorescenc yield isω 3=0·36±0·04, correspondingly. A further application of the experimental method is described.

    Description / Table of Contents: The corrosion resistance of titanium in nitric acid of high temperaturesCorrosion tests showed that, in nitric acid of a concentration ranging from 20 to 70 percent. and at temperatures ranging from 190 to 230° C, titanium has a corrosion rate of between 1 and 10mm pr. annum. This high corrosion rate can be avoided if a substance containing silicon is added to the nitric acid.
    Notes: Korrosionsversuche ergaben, daß Titan in Salpetersäure der Konzentrationen 20 bis 70% bei Temperaturen von 190 bis 230° C rnit Geschwindigkeiten zwischen 1 bis 10 mm/Jhr. abgetragen wird. Diese starke Korrosion läßt sich unterbinden, wenn der Salpetersäure eine siliciumhaltige-Substanz zugesetzt wird.
