Experimental differential cross-section (DCS) ratios for the above transitions to the 1{sup 1}S {r_arrow} 2{sup 1}P transition are reported at impact energies of 30eV, 40eV and 80eV and scattering angles in the range of 5{degrees} to 130{degrees}. The data are an extension of previously reported work using the electron-photon coincidence method in the VUV. The DCS ratios are normalized to available absolute DCSs for the 1{sup 1}S {r_arrow} 2{sup 1}P transition and the resulting n{sup 1}P DCSs are compared to previous semi-empirical DCSs as well as available theory.
