Problem of quasistationary state decay for the potential well separated from the external area by potential barrier is considered. On the basis of the solution of timedependent Schrödinger equation, the general analytic expression for the quasistationary state width is obtained in the case when the potential well is surrounded by the potential barrier of the sufficient height or sufficient width.
