Scientific paper

IUE HR spectra of four cool CP stars have been analyzed to search for the Be II 3130 - 3131 resonance doublet. No large overabundances similar to those found in some Hg-Mn stars have been found. Two of the stars analyzed were previously found as Li overabundant, suggesting different behaviours of the two elements. Predictions of Li overabundance and Be underabundance by microscopic diffusion have been advanced for stars of two solar masses, but in absence of a magnetic field.
