We present total and partial electron capture cross sections for Ne$^{10+}$ + H(1s) collisions at energies from 0.01 eV to 1 keV using the hyperspherical close-coupling method (HSCC). Good agreements with the previous calculations by the classical trajectory Monte-Carlo (CTMC) method are found for total capture cross section, but not for partial cross sections, especially below about 200 eV/amu. We found that the total cross section is mainly due to the population of the n=7 channels, and only at energies above 50 eV/amu n=5, 6 channels begin to contribute to the total cross section.
