Lithium on the surface of cool magnetic CP stars. II. Spectrum analysis ofHD 83368 and HD 60435 with lithium spots

As a further step in our Lithium project we present results of abundance de termination of some elements in the roAp star HD 60435. Possible NLTE effec ts were considered. Equivalent widths of spectral lines vary with rotationa l phase which suggests nonuniform distribution of chemical elements over th e stars' surface. Large abundance differences derived from various ions of some rare earth elements indicate their possible vertical stratification. T wo spots of enhanced lithium abundance were distinguished at the magnetic p oles on HD 60435 and their parameters derived. The rotational axis inclinat ion i = 133 degrees or 47 degrees and surface magnetic field H-s = 3 +/- 1 kG were determined for the first time for HD 60435. The results are compare d with HD83368, the other star with lines of lithium remarkably variable in intensity and wavelength.
