Benchmark calculations for electron collisions with neutral indium atoms.

Cross sections for electron collisions with indium atoms are important for modelling plasmas with indium as a constituent. However, only a few experimental data and previous calculations are currently available, without a thorough uncertainty assessment. As part of a multi-author, multi-institutional collaboration [1] with the goal of recommending a set of cross sections for elastic scattering, momentum transfer, excitation, and ionization for e-In collisions, we carried out extensive relativistic Dirac B-spline R-matrix and convergent close-coupling calculations. Very good agreement between the predictions is obtained, as long as inner-shell excitation or excitation-ionization processes involving the 5s-subshell can be neglected. \hbox{[1]~K.~R.~Hamilton}, O.~Zatsarinny, K.~Bartschat, M.~S.~Rabasovi\'{c}, D.~\v{S}evi\'{c}, B.~P.~Marinkovi\'{c}, S.~Dujko, J.~Atic, D.~V.~Fursa, I.~Bray, R.~P.~McEachran, F.~Blanco, G.~Garc\'{i}a, P.~W.~Stokes, R.~D.~White, and M.~J.~Brunger; in preparation for Phys.\ Rev.~A., J.~Phys.\ Chem.\ Ref.\ Data, Plasma Sources Sci.\ Technol.
