ResumoAbsolute gf values for 41 lines of Cr i and 2 lines of Cr ii have been determined from measurements of shock-heated gas emission. The lines are distributed over 12 multiplets and fall in the spectral range 3805-5410Å. The values presented here show disagreement with those reported by other investigators on an absolute scale ranging from a few percent to factors of approximately 10. Application of the gf values to computed solar abundances is discussed.
