We prove the existence of an orbifold Kähler-Einstein metric on a general hypersurface in $\mathbb P(1^3,2,2)$ of degree 6 and a general hypersurface in $\mathbb P(1^3,2,3)$ of degree 7. Bibliography: 50 titles.
Keywords: Fano varieties, log-canonical threshold
Mots-clés : Kähler-Einstein metric, Tian alpha-invariant.
