... 1/σn, understanding that the mean-free path will always be given by a suitably defined cross-section σ, so that λ = (σn)−1 gives the correct expression for the mean free path. In the same way, we can define a mean free time τ between collisions by τ = λ/v, where v is the mean speed of the particles. ...
