This paper examines the mass dependences of vibrationally inelastic integral state-to-state cross sections for the helium-hydrogenic scattering system. The cross sections are calculated within the coupled states-exponential distorted wave (CS-EDW) approximation, and are analyzed along with the conceptually simpler distorted wave (CS-DW) cross sections. Quantitative links between the EDW and DW results are made by means of component (or channel coupling) sensitivity coefficients, which measure the sensitivity of a given EDW cross section to the potential matrix elements coupling any two states.
