Abstract
The isovector dipole strength in 92-100Mo is analysed within the self-consistent separable random-phase approximation model with Skyme forces with four different parametrizations. We show that, due to the compensation effect, the influence of nuclear deformation on E1 strength below 10-12 MeV is quite modest.
The four Skyrme forces differ in description of the whole giant resonance but give rather similar results below 12 Mev (region important for understanding of astrophysical processes).
