Popis:	The l‐average CS and IOS approximations are extended to treat fine structure transitions in 2P atom–1S atom scattering. Calculations of degeneracy averaged probabilities and differential cross sections for Na(2P)+He(1S) collisions in the CS and IOS methods agree well with the CC results. The present nonunitarized form of the CS approximation fails to properly predict all of the jm→j′m′ sections and in particular leads to a selection rule forbidding jm→j–m transitions for j=half‐odd integer values.
