    "abstract": "A combination of the variable-constant and complex coordinate rotation\nmethods is used to solve the two-body Schr\\\"odinger equation. The latter is\nreplaced by a system of linear first-order differential equations, which\nenables one to perform direct calculation of the Jost function for all complex\nmomenta of physical interest, including the spectral points corresponding to\nbound and resonance states. Explicit forms of the equations, appropriate for\ncentral, noncentral, and Coulomb-tailed potentials are given. Within the\nproposed method, the scattering, bound, virtual, and resonance state problems\ncan be treated in a unified way. The effectiveness of the method is\ndemonstrated by a numerical example.",
