In view of the crucial importance of thermal transport for the hydrodynamic efficiency of inertial fusion, a complementary approach to the well established x-ray method for burnthrough measurements had been proposed using longer wavelength lines. Basically, this will allow access to a lower temperature region, possibly including some preheat. As proposed, a theoretical program was initiated to enhance the University of Rochester computer code by adding the various atomic processes needed to calculate quantitatively lithium-like line spectra. We contributed to the University of Rochester program through our various tests of atomic physics packages in LILAC. In April 1986, successful measurements were made for aluminum and titanium targets overcoated with up to 9 to 11 ..mu..m, respectively, of CH. A description of these measurements and of the conclusions reached by comparison with the code simulation constitutes the bulk of this report.
