Scientific paper

The surface distribution of five elements: iron, chromium, titanium,
magnesium and manganese on the magnetic A0pCr star epsilon UMa, have been
calculated using the Doppler imaging technique. We found that iron, chromium
and manganese are correlated with the assumed dipole magnetic field geometry of
this star, which is apparently not the case of magnesium and titanium.
