4. Since the mean free path was defined for a state in which the Ni’s were equal, it would perhaps be more rigorous to use state (b) as the reference state instead of (a). It is usual, however, to refer the shock thickness to λa, and in the present case it seems justified to apply formally the equation λ = 3∕(1+22)Sn in state (a).
