Abstract Absolute line strengths and transition probabilities are calculated in the domain of intermediate coupling for the transition array s2p2-sp3 in Ca xv and Fe xiii. The dipole integrals as well as the energy parameters are calculated from the Hartree-Fock program of Dr. Charlotte Froese. Extrapolated wavelengths are given where sufficient empirical data are available; otherwise, theoretical Hartree-Fock energies are used to compute the wavelengths. The results clearly indicate the necessity for the use of intermediate coupling results where coronal statistical equilibrium problems are concerned. Several lines forbidden in LS coupling show strengths comparable to allowed resonance lines and should, therefore, be observable in the extreme ultraviolet spectrum of the solar corona.
