International audience; Phobos and Deimos, the two small satellites of Mars, are thought either to be asteroids captured by the planet or to have formed in a disc of debris surrounding Mars following a giant impact. Both scenarios, however, have been

Publikováno v: Journal of Physics B: Atomic, Molecular and Optical Physics. 37:1305-1320
The scattering of low-energy electrons by helium in the presence of a CO2 laser field is studied using the R-matrix Floquet theory. Two target states are retained in the calculations, the 1S ground state and a 1Po pseudostate optimized to describe th
