Electron Impact Excitation Collision Strengths for Fine-Structure Transitions in of Fe IX*

New extensive calculations are performed for electron collision strengths and transitions probabilities for a wide range of transitions in Fe IX. The collision strengths are calculated in the close-coupling approximation using the B-spline Breit-Pauli R-matrix method. The multiconfiguration Hartree-Fock method in conjunction with B-spline expansions is employed for an accurate representation of the target wave-functions. The close-coupling expansion includes 370 fine-structure levels of Fe IX in energy region up to $3p^55s$ states. It includes levels of the $3p^6$, $3p^53d,4l,5s$, $3s3p^63d,4s,4p$, $3p^43d^2$, $3s3p^53d^2$ configurations and some low-lying levels of the $3p^33d^3$ configuration. The effective collision strengths are obtained by averaging the electron collision strengths over a Maxwellian distribution of velocities at electron temperatures in the range from 10$^4$ to 10$^7$ K. There is a good agreement with the previous R-matrix calculation for transitions between first 17 levels of the $3p^6$, $3p^53d$ and $3s3p^63d$ configurations. The present results considerably expand the existing data sets for Fe IX, allowing more detailed treatment of the available measured spectra from different space observatories.
