DEVELOPMENTS AND COMPARISON OF 2 DENIM OPACITY MODELS

Local Thermodynamic Equilibrium (LTE) opacity codes have been develope d at DENIM during the last years. JIMENA [1,2] is an opacity code that solves self-consistently, for each temperature and density, the radia l Dirac equation with a local spherically symmetrical potential. Very recently we have developed a new opacity code, called ANALOP, that use s an analytical potential [3], which can include density and temperatu re effects for atomic data calculations. Opacities are determined with these two codes for selected elements at different plasma conditions. (C) 1998 Elsevier Science B.V. All rights reserved.
