Abstract
We present the position-momentum uncertainties for the Pöschl-Teller potential. We observe that the Îx decreases with the potential depth λ but increases with quantum number n. Interestingly, we find that the Îp first increases and then decreases with the n. The ÎxÎp first decreases and then increases with the λ, but almost becomes a constant (n+1/2)â for a larger λ. Particularly, there exists a squeezed phenomenon in position x for the lower states. The squeezing in x compensated for by an increase in momentum p, such that ÎxÎp⩾â/2 is still satisfied.
