Abstract
In this communication we remodel the analysis of the Bethe-ansatz for the nonlinear Schrödinger equation in an external field. We have constructed the n-particle wave function, demonstrated the factorization of the S-matrix for n=2, 3 and 4 with the important difference that the basic 2-body S-matrix is not a single matrix but two matrices, and verified the Yang-Baxter equation.
