21. The system with L=9 also exhibits a clear tendency towards unbinding, however, no level crossing but rather a crossover between the two regimes occurs. For L = 11, a level crossing is found, with the total momentum jumping from 0 to a finite value near 0, whereas in the even systems the total momentum changes from 0 to a value near π. In view of these odd-even effect, we restrict the discussion to finite ladders with an even number of rungs.
