Abstract : In this final report, we present the infrared spectrum of a laser produced oxygen plasma. We have focused on extending the spectral range of observation of Ol Rydberg emissions to 13 micrometers. We report the first observations of OI Rydberg line emission in the 8-13 micrometer wavelength region. We also present observations of Bremsstrahlung emission that compare favorably with recent theoretical results of Lin. We have developed a model called APOSTLE which predicts the line broadened emission spectrum from an OI plasma. We describe the theoretical and functional basis for the model. The model results are discussed and compared with the data obtained in the plasma experiment.
