    "abstract": "A generalized contour deformation method (GCDM) which combines complex\nrotation and translation in momentum space, is discussed. GCDM gives accurate\nresults for bound, virtual (antibound), resonant and scattering states starting\nwith a realistic nucleon-nucleon interaction. It provides a basis for full\noff-shell $t$-matrix calculations both for real and complex input energies.\nResults for both spectral structures and scattering amplitudes compare\nperfectly well with exact values for the separable Yamaguchi potential.\nAccurate calculation of virtual states in the Malfliet-Tjon and the realistic\nCD-Bonn nucleon-nucleon interactions are presented.\n  GCDM is also a promising method for the computation of in-medium properties\nsuch as the resummation of particle-particle and particle-hole diagrams in\ninfinite nuclear matter. Implications for in-medium scattering are discussed.",
