    "abstract": "An exact method for direct calculation of the Jost functions and Jost\nsolutions for non-central potentials which couple partial waves of different\nangular momenta is presented. A combination of the variable-constant method\nwith the complex coordinate rotation is used to replace the matrix\nSchr\\\"odinger equation by an equivalent system of linear first--order\ndifferential equations. Solving these equations numerically, the Jost functions\ncan be obtained to any desired accuracy for all complex momenta of physical\ninterest, including the spectral points corresponding to bound and resonant\nstates. The effectiveness of the method is demonstrated using the Reid\nsoft-core and Moscow nucleon-nucleon potentials which involve tensor forces.",
