Shock‐Tube Measurements of Cr i and Cr ii gf Values

Absolute 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 3805‐5410A. 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.
