    "abstract": "A new spectral type method for solving the one dimensional quantum-mechanical\nLippmann-Schwinger integral equation in configuration space is described. The\nradial interval is divided into partitions, not necessarily of equal length.\nTwo independent local solutions of the integral equation are obtained in each\ninterval via Clenshaw-Curtis quadrature in terms of Chebyshev Polynomials. The\nlocal solutions are then combined into a global solution by solving a matrix\nequation for the coefficients. This matrix is sparse and the equation is easily\nsoluble. The method shows excellent numerical stability, as is demonstrated by\nseveral numerical examples.",
