# LSFBTR: A subroutine for calculating spherical bessel transforms

## Description

Title of program: LSFBTR Catalogue Id: AANZ_v1_0 Nature of problem Transforming an angular momentum wave function from coordinate to momentum representation requires the calculation of Hankel transforms for spherical Bessel functions. This subroutine calculates such integrals when the function to be transformed is given numerically at r values that are distributed uniformly in the variable ln(r). The resulting values of the transform are given at k values distributed uniformly in the variable ln(k).
