               <mods:abstract>We prove Pitt and Boas'\'' type inequalities for products of radial functions and spherical harmonics in $ \R^n$ . In the process, we obtain upper and lower estimates of the operator norm of the Hankel transform with power weights. Our inequalities are sharp in some specific cases.</mods:abstract>
