  The lines of lithium at 6708 A, and 6103 A, are analyzed in high resolution
spectra of some sharp-lined and slowly rotating roAp stars. Three spectral
synthesis codes - STARSP, ZEEMAN2 and SYNTHM were used. New lines of the rare
earth elements from the DREAM database, and lines calculated on the basis of
the NIST energy levels were included. Magnetic splitting and other line
broadening processes were taken into account. Enhanced abundances of lithium in
the atmospheres of the stars studied are obtained for both the lithium lines.
High estimates of 6Li/7Li ratio (0.2 -- 0.5) for the studied star can be
explained by Galactic Cosmic Ray (GCR) production through the spallation
reactions and the preservation of the original $^6$Li and $^7$Li by the strong
magnetic fields.
