Abstract
A complete system of primitive pairwise orthogonal idempotents for cyclotomic Hecke algebras is constructed by consecutive evaluations of a rational function in several variables on quantum contents of multi-tableaux. This function is a product of two terms, one of which depends only on the shape of the multi-tableau and is proportional to the inverse of the corresponding Schur element.

Key words: cyclotomic Hecke algebras; fusion formula; idempotents; Young tableaux; Jucys-Murphy elements; Schur element.
