Effective collision strengths for electron-impact excitation of Al10+

  • V. STANCALIE (a1) and V. PAIS (a1) (a2)

Electron collision strengths for electron-impact excitation of Li-like and Al ion are evaluated in close-coupling approximation using the multi-channel R-matrix method. Five LS target eigenstates are included in the expansion of the total wave function, consisting of the two n = 2 states with configurations of 1s22s, 1s22p, and three n = 3 states with configurations 1s23s, 1s23p, and 1s23d. Collision strengths are obtained in LS coupling using FARM code and in intermediate coupling scheme using the SUPERSTRUCTURE program. The effective collision strengths are calculated as function of temperature, up to a temperature that does not exceed half of the maximum energy in the R-matrix run.
