    "abstract": "We investigate the use of stochastic methods for zero energy quantum\nscattering based on a path integral approach. With the application to the\nscattering of a projectile from a nuclear many body target in mind, we use the\npotential scattering of a particle as a test for the accuracy and efficiency of\nseveral methods. To be able to deal with complex potentials, we introduce a\npath sampling action and a modified scattering observable. The approaches\nconsidered are the random walk, where the points of a path are sequentially\ngenerated, and the Langevin algorithm, which updates an entire path. Several\nimprovements are investigated. A cluster algorithm for dealing with scattering\nproblems is finally proposed, which shows the best accuracy and stability.",
