Two-photon transition amplitudes for bound-to-bound transitions in hydrogen are calculated for the most general exponential cosine screened Coulomb (MGECSC) potential which is of relevance in many branches of physics. The variation in transition amplitude with different potential parameters is investigated. Enhancement in the transition amplitudes is observed when, on absorption of a single photon, the system is in resonance with an intermediate level. To the best of the knowledge of the author, the MGECSC potential has not been applied previously to the problem of two-photon excitation.
