Dunning's amd Hay's electronic potential curves were used to compute transition moments and to predict emission profiles for comparison with the observed fluorescence spectra. By adjusting the ionic and valence states by 8 nm, many of the observed spectral features can be quantitatively accounted for. The synthetic spectrum of KrF includes the 220-nm D/sub /sup 1///sub 2// ..-->.. X transition, the 249-nm composite feature, and the 276-nm feature which is a superposition of the nearly coincident C/sub /sup 3///sub 2// ..-->.. A/sub /sup 3///sub 2// and B/sub /sup 1///sub 2// ..-->.. /sub /sup 1///sub 2// transitions. The feature observed at 300 nm by Powell and Murray is likely due to a transition from the /sup 2/..sigma../sup +//sub /sup 1///sub 2// Rydberg state to the repulsive A/sub /sup 1///sub 2// state. The 400-nm feature may be due to a triatomic complex. (DLC)

The SHIVA laser is a 20 beam Nd-doped glass laser designed to provide various irradiation geometries for fusion pellets. The general objective of the SHIVA laser is to achieve significant thermonuclear burn or about 1 percent of scientific breakeven by isentropic compression. Descriptions are given of the laser system, physical configuration, alignment system, and the computer control system. (MOW)
