The profile after passing through the germanium is spatially smaller, but much less intense. Following irradiation, the samples were allowed to decay for 25 minutes before initiating a 12-minute count using a pair of high-resolution germanium detectors. Accurate wavelength determination of the lasing and non lasing lines in laser-produced germanium plasma. For example, one of the rare and useful metals, eminently useful to-day—indeed, it is the basis of the modern transistor industry—is germanium.
