Description

The new candidate in spotty lihtiumy stars is found out. The group of roАр stars with small rotary variability and large contents of REE and strong magnetic fields is investigated. The high contents of lithium at stars of this group and especially the relation of isotopes can be explained by manufacture of lithium in reactions of spliting and preservation of Li7 and Li6 by strong magnetic field in this stars. Distinctions in the contents of lithium on lines 6103А and 6708 A testifies to vertical stratification of lithium.
