摘要：

Numerical schemes for the evaluation of Fourier transforms with Gauss-Laguerre quadratures are presented. These schemes which incorporate functional values at complex arguments are tested for efficacy and accuracy. We illustrate their effectiveness on a simple model system by computing the form factor and its Laplacian for the neon atom.
