摘要：

We investigate three different numerical representations for nuclear mean-field calculations: finite differences, Fourier representation, and basis-splines. We compare these schemes with respect to precision and speed. It turns out that Fourier techniques and basis-splines are much superior in precision to finite differences. The Fourier representation in connection with the fast Fourier transformation is advantageous for large grids whereas matrix techniques, derived either from basis-splines or from Fourier representation, are preferable for smaller grids. © 1992.
