We carried out a detailed analysis of spectra of the unique roAp star HD 101065 ( Przybylski ’ s star ) near the resonance doublet Li I 6708 Å , using a most complete line list including all possible transitions between REE levels of NIST database .
Our model calculations were performed under two assumptions : blend of Li and REE lines , and blend of REE lines only .
They prove that Li lines are present in the range 6707.72 - 6708.02 Å and that the resulting Li abundance is 3.1 dex ( in the scale \log N ( H ) = 12.0 ) , while the isotopic ratio ^ { 6 } Li / ^ { 7 } Li is near to 0.3 .
