Atomic data and spectral line intensities for highly ionized tungsten (Co-like W47+ to Rb-like W37+) in a high-temperature, low-density plasma

Calculated transition wavelengths, oscillator strengths, and collisional-radiative line intensities are presented for the 11 tungsten (Z = 74) ions from Co-like W47+ to Rb-like W37+. Fully relativistic, ab initio calculations have been carried out for the ion structure in each case, and a detailed collisional-radiative model has been constructed. Electric and magnetic dipole and quadrupole (E1, M1, E2, and M2) transitions are considered, and references are given to continuing experiments where the present tungsten emission features may be observed.
