    "abstract": "A method to compute the bound state eigenvalues and eigenfunctions of a\nSchr\\\"{o}dinger equation or a spinless Salpeter equation with central\ninteraction is presented. This method is the generalization to the\nthree-dimensional case of the Fourier grid Hamiltonian method for\none-dimensional Schr\\\"{o}dinger equation. It requires only the evaluation of\nthe potential at equally spaced grid points and yields the radial part of the\neigenfunctions at the same grid points. It can be easily extended to the case\nof coupled channel equations and to the case of non-local interactions.",
