Bound-bound transitions in hydrogen-like ions in dense quantum plasmas

The properties of bound-bound transitions in hydrogen-like ions in dense quantum plasmas, characterized by a cosine-Debye-Huckel interaction between charged particles, are studied in detail. The transition frequencies, oscillator strengths, and radiative transition probabilities of Lyman and Balmer series are calculated for a wide range of screening strengths of the interaction up to the n = 5 shell. For Delta n not equal 0 transitions, all these quantities exhibit a significant decrease with increasing screening strength, while for the Delta n = 0 transitions and for the radiative lifetimes, the opposite is true. The present results are compared with those available from the literature. They are also compared with the results for the pure Debye-Huckel potential with the same screening strength.
