With the use of a variant of the method of separation of variables, the initial value problem for the time-dependent linear
Schršodinger equation is solved exactly for a large class of potential functions related to multisoliton interactions in the vector
nonlinear Schršodinger equation. Completeness of states is proved for absolutely continuous initial data in L1. Copyright ©
