The quantum close-coupling studies of the 3P j=23P j=1 non-adiabatic transition in Ca colliding with He and Ar are presented. The multistructure cross sections are calculated using the pseudopotential curves of E. Czuchaj, M. Krośnicki, H. Stoll, Chem. Phys. 101, 292 (2003). The conventional and coherence cross sections that can be measured in collisional experiments with atomic beams are expressed via generalized Grawert parameters, quantities dependent on dynamics only and independent of geometry. They allow us to obtain direct relationships between the average cross sections and the conventional and coherence cross sections. The possibility of experimental determination of reorientation, alignment and other non-adiabatic effects occuring during atomic collisions is discussed.
