Recent experiments on electron capture from elliptic Rydberg states by Ehrenreich et al. have shown that the total electron capture cross section, {sigma}, depends strongly on the eccentricity, e, of the elliptic state and the orbit direction of the electron. The authors present the results of close-coupling calculations carried out for protons colliding with elliptic H(n=3,4,5) atoms, which show that the dependence of {sigma} on e varies weakly with the principal quantum number n. The dependence of {sigma} on the angle, {phi}, between the beam and the classical plane of the elliptic orbital is also presented. The results are shown to be consistent with the criteria of velocity matching for the electron capture process.
