Recent observations of the absorption and emission spectra of electron-bombarded liquid helium and the development of a detailed model describing the state of an excited atomic species in liquid helium have made it desirable to have a method of computing spectral line properties from the model. In this work we have investigated the application of static line broadening theory when a nonspherical, numerical potential and a nonspherical distribution are required and the theory is to be employed at high densities. Techniques for the application of the intensity expression and analysis of computed spectral lines are performed for several model distributions and potentials. The results of computations using the Hickman model are compared with the observed spectra.
