Research line 1: A summary of my research in electron-molecule scattering can be found in the review article: Romarly F. da Costa, Márcio T. do N. Varella, Márcio H. F. Bettega, and Marco A. P. Lima, “Recent advances in the application of the Schwinger multichannel method with pseudopotentials to electron-molecule collisions”, Eur. Phys. J. D 69, 1 (2015). DOI: 10.1140/epjd/e2015-60192-6. This paper reviews several applications of the method using pseudo-potentials after the first publication on the subject: Márcio H. F. Bettega, Luiz G. Ferreira, and Marco A. P. Lima, “Transferability of Local-Density Norm-Conserving Pseudopotentials to Electron-Molecule Collision Calculations,” Phys. Rev. A 47, 1111-8 (1993). DOI: http://dx.doi.org/10.1103/PhysRevA.47.1111
Research line 2: In positron-molecule scattering theory and applications, the first paper was: José S. E. Germano and Marco A. P. Lima, “The Schwinger Multichannel Method for Positron-Molecule Scattering,” Phys. Rev. A 47, 3976-82 (1993). DOI: http://dx.doi.org/10.1103/PhysRevA.47.3976. Many papers came after that.
