Using the WKB approximation, we have solved a problem concerning reflection of a particle from the potential well U(x) = -U<sub>0</sub>cosh <sup>-2</sup>(x/a). This enables us to give a simple interpretation of the fact that for some values of the potential amplitude U<sub>0</sub>, the particle is not reflected from such a potential.
