Iron Project. XLIII. Fe V

The Breit-Pauli R-matrix (BPRM) method is used to calculate 1.46x10^6^ oscillator strengths for the allowed and intercombination E1 transitions among 3865 fine-structure levels dominated by configuration complexes with n<=10 and l<=9. These data are complemented by an atomic structure configuration interaction (CI) calculation using the SUPERSTRUCTURE program for 362 relativistic quadrupole (E2) and magnetic dipole (M1) transitions among 65 low-lying levels dominated by the 3d^4^ and 3d^3^ 4s configurations.

Procedures have been developed for the identification of the large number of fine-structure levels and transitions obtained through the BPRM calculations. The target ion Fe VI is represented by an eigenfunction expansion of 19 fine-structure levels of 3d^3^ and a set of correlation configurations. Fe V bound levels are obtained with angular and spin symmetries SL{pi} and J{pi} of the (e + Fe VI) system such that 2S+1=5, 3, 1, L<=10, J<=8 of even and odd parities.
