[en] It has been suggested to use the production of Λ hyperons for investigating the nucleon spin structure. The viability of this idea depends crucially on the spin structure of the Λ. Using nonperturbatively O(a) improved Wilson fermions in the quenched approximation we have studied matrix elements of two-quark operators in the Λ. We present results for the axial vector current, which give us the contributions of the u, d, and s quarks to the Λ spin
