Statistics and morphology of typical damages of the foil and its resistance to fluorine etching were investigated.
A more potent device may be a mixture of liquid fluorine and hydrogen at very low temperatures.
This can be seen as a continuum superimposed on fluorine ion lines.
The compositions of magmatic phlogopite and apatite indicate the presence of water and fluorine in the melt.
The continuum appearing at higher energy is mainly due to fluorine ions.
However, fluorine and chlorine will be the easiest gases to use for any initial tests of available negative ion current densities from practical sources.
Fluorine is highly mobile and can be rapidly flushed from the affected areas by rainfall.
Fluorine-i8 labelled flurodeoxyglucose has been shown to be effective in differentiating malignant from benign tumours and in determining the extent of disease.
