%D 2014 %T Ionization cross-sections for positron collisions with N2 %V 68 %A G Laricchia %A DA Cooke %A DJ Murtagh %X The total and direct ionization cross-sections for positron impact on molecular nitrogen have been measured in the energy range from 5 eV to 850 eV. The results are compared with other experimental and theoretical determinations. %O This is an open access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. %J European Physical Journal D %L discovery1418542
