  Absorption and emission spectra of plasmas with multicharged-ions contain
transition arrays with a huge number of coalescent electric-dipole (E1) lines,
which are well suited for treatment by the unresolved transition array and
derivative methods. But, some transition arrays show detailed features whose
description requires diagonalization of the Hamiltonian matrix. We developed a
hybrid opacity code, called SCORCG, which combines statistical approaches with
fine-structure calculations consistently. Data required for the computation of
detailed transition arrays (atomic configurations and atomic radial integrals)
are calculated by the super-configuration code SCO (Super-Configuration
Opacity), which provides an accurate description of the plasma screening
effects on the wave-functions. Level energies as well as position and strength
of spectral lines are computed by an adapted RCG routine of R. D. Cowan. The
resulting code provides opacities for hot plasmas and can handle mid-Z
elements. The code is also a powerful tool for the interpretation of recent
laser and Z-pinch experimental spectra, as well as for validation of
statistical methods.
