A full spectrum analysis based on the noise adjusted singular value decomposition method for the description of the time-variable background and adjustment calculations is a possible analysis method, which may provide advantages compared with a peak-based analysis, if applied to a time series of gamma spectra. An analysis example is shown and discussed with a measured time series of gamma spectra obtained from a spectroscopic gamma detector with a NaI(Tl) scintillator as it is used in the environmental radiation monitoring.",

However, almost 50 years after the invention of the laser the spectral region that can be investigated in this way is still restricted to wavelengths below the near ultraviolet. The much larger spectral band of the extreme ultraviolet (XUV), where many fundamental transitions of say hydrogen like ions reside, is thus far unexplored by high precision laser spectroscopy. One possible route to narrow band radiation in this region could be the use of high order harmonics generated with short laser pulses of high repetition rate focused in a gas jet. Meanwhile mu W power levels in the XUV at multi-MHz repetition rates have been demonstrated which are the main prerequisites for this method. The 1S-2S two photon transition at 60 nm in singly ionized helium is a rewarding candidate because it allows sensitive tests of quantum electrodynamics.}",
