Scientific paper

We propose to observe Li I 6708 at different well distributed rotational phases in four cool Ap stars and two standard stars (Iota Peg and Alpha CMi). The purpose is to obtain the lithium abundance at each phase, taking into account the effect of the magnetic field. Observations with high spectral resolution and high S/N ratio should help to solve the problem of lithium presence in Cp stars, evaluate its abundance, elucidate the behavior of the lithium blend in the spectra of Cp stars in relation to a star's peculiarity, and investigate the magnetic field structure and rotation of Cp stars. (Abstract only).
