N2 - We report the first quantitative differential and integral cross sections (DCSs and ICSs) for the unfolded lowest-lying triplet and singlet transitions near threshold energies in ammonia molecule by electron impact at 9.8, 12, and 15 eV for the scattering angles of 10° to 130°. The DCS are shown to be typical of forward scattering for the singlet and isotropic for the triplet transitions, respectively. Towards the threshold energy, the ICS for the singlet state exhibits a monotonically decreasing feature, whereas a sharp increase is expected for the triplet state, which are compared with the R-matrix calculations from the literature.
