dc.descriptionWe study the dependencies of spin asymmetries in diffractive leptoproduction on the spin structure of the pomeron coupling. It is shown that the $A_{ll}$ asymmetry in diffractive processes is proportional to the fraction of the initial proton momentum $x_p$ carried off by the pomeron. The resulting asymmetries decrease with increasing energy for diffractive $J/Ψ$ production and are energy independent for diffractive $Q \bar Q$ leptoproduction. The connection of these asymmetries with the non-forward gluon distribution in the proton is discussed.
