Recombination line intensities for hydrogenic ions - II. Case B calculations for C VI, N VII and O VIII

The intensities of recombination lines of C VI, N VII and O VIII are calculated, accounting for both electron and heavy particle collisions and assuming Case B of Baker & Menzel. The intensities of lines formed by transitions |n_ u→ nₗ|⁠, are tabulated for nu≼50, nl≼29, at log Ne=4(l)13 and at 10 values of electron temperature in the interval 10 000 K≼Te≼500 000 K.
