Description
We report electric quadrupole and magnetic dipole transitions among the levels belonging to 3d^6^4s, 3d^7^ and 3d^5^4s^2^ configurations of Fe II in a large scale configuration interaction (CI) calculation. The CIV3 code developed by Hibbert and coworkers is used to determine configuration interaction wave functions for these levels: for the optimisation of two different sets of orbitals based on alternative choices of the 3d function, for creating and diagonalising the Hamiltonian matrices and finally for calculating transition probabilities.
