  The discrete variable representation (DVR) basis is nearly optimal for
numerically representing wave functions in nuclear physics: Suitable problems
enjoy exponential convergence, yet the Hamiltonian remains sparse. We show that
one can often use smaller basis sets than with the traditional harmonic
oscillator basis, and still benefit from the simple analytic properties of the
DVR bases which requires no overlap integrals, simply permit using various
Jacobi coordinates, and admit straightforward analyses of the ultraviolet and
infrared convergence properties.
