SUMMARY
The hard sphere collision cross section for three-body systems is established as always equal to zero in classical physics due to the improbability of simultaneous contact among three bodies. In quantum systems, the cross section is influenced by particle speeds and energy bound states, complicating the analysis. The discussion highlights the need for clarity on whether the context is classical or quantum mechanics when addressing collision cross sections.
