Integrals of highly oscillatory integrands are considered which contain either a factor exp(ik-a)x or a product of spherical Bessel functions. Using Cauchy's theorems the line of integration is changed from the positive real axis to a suitable inclined line in the complex plane which yields a rapidly converging integral.
