This morning I've been thinking about a simple problem whose I can't find out a satisfying solution. We all know that two "close" fermions can't exist in a up-up or down-down spin configuration because of vanishing state function as expressed by the exclusion principle.
But what does *practically* happen when I try to collide two up-up fermions, maybe with an accelerator? I've encountered several times the vague concept of a "Pauli repulsion force" in studies about atomic structure but is it a misurable force - i.e. real - or just an emergent property of the system itself? Or am I missing something obvious?
Thanks in advance,
Valleyman
