    "abstract": "Modern cosmic ray transport codes, that are capable of use for a variety of\napplications, need to include all significant atomic, nuclear and particle\nreactions at a variety of energies. Lepton pair production from nucleus-nucleus\ncollisions has not been included in transport codes to date. Using the methods\nof Baur, Bertulani and Baron, the present paper provides estimates of\nelectron-positron pair production cross sections for nuclei and energies\nrelevant to cosmic ray transport. It is shown that the cross sections are large\ncompared to other typical processes such as single neutron removal due to\nstrong or electromagnetic interactions. Therefore lepton pair production may\nneed to be included in some transport code applications involving MeV\nelectrons.",
