Abstract
Spectral emission from plasmas produced by ruby or Nd laser impact on an Al target was studied in the 100–200‐Å region using both flow proportional counter and photographic techniques. The maximum intensities of continuous and Al IV line emissions were found to occur in quite different spatial zones of the plasma. The results are compared with those for Al V and Al VI spectra. From the appearance times of the 160.073‐Å Al IV line a value of 107 cm sec−1 was obtained for the expansion velocity of the plasma.Keywords
