Aluminum Plasma

A theoretical analysis studied was performed to study the opacity broadening of spectral lines emitted from aluminum plasma produced by Nd-YLF laser. The plasma density was in the range 1028-1026 )) m-3 with length of plasma about ?300) m) , the opacity was studied as function of plasma density & principle quantum number. The results show that the opacity broadening increases as plasma density increases & decreases with the spacing between energy levels of emission spectral line.

Atomic Energy Levels

The energy levels of zinc III have been revised and extended as a result of improved wavelengths of the spectral lines, particularly those in the vacuum ultraviolet. Of the 70 levels listed in Atomic Energy Levels (Moore 1952), 37 have been retained in the present analysis, although the designations of 14 of these have been changed. An additional 233 levels are established. The new scheme results in 1279 line classifications in the region from λ 383 Å to λ 6270 Å. A value of 320 390 cm−1 is given for the ionization potential of Zn III.
