LINO, Jorge L.S.. Elastic scattering of low-energy electrons from ammonia. Rev. mex. fis. [online]. 2005, vol.51, n.1, pp.100-103. ISSN 0035-001X.

We report an application of the Schwinger variational principle with plane waves as a trial basis set [J.L.S. Lino, M.A.P. Lima, Braz. J. Phys. 32, 432 (2000)]. Differential cross sections are obtained for electron-NH₃ collisions from 8.5 to 30 eV. Differential cross sections are found to be in reasonable agreement with existing measurements.
