Talk:Nuclear interaction length

The first definition is trivially incorrect. In the early stages of a hadronic shower, the number of particles increases. At best, a definition based on a reduction in the number of particles could only be valid in the later stages of a shower. The mean free path definition is the correct one. — Preceding unsigned comment added by 134.107.2.119 (talk) 08:45, 12 December 2014 (UTC)
