Abstract: In this paper, the asymptotic expansion of integrals of the form $ \int_0^\infty {F(kr)f(k)dk} $ s considered, as $ r$ tends to infinity, and where $ F(kr)$ are Bessel functions of the first and second kind, or functions closely related to these. Asymptotic expansions for several functions of this type are presented under suitable restrictions on $ f(k)$. The expansion given by Willis for Hankel transforms is seen to be valid under conditions of $ f(k)$ less restrictive than those imposed by that author.
