Let (M, g) be an n−dimensional Riemannian manifold and T
∗M be
its cotangent bundle equipped with a Riemannian metric of CheegerGromoll type which rescale the horizontal part by a positive differentiable function. The main purpose of the present paper is to discuss
curvature properties of T
∗M and construct almost paracomplex Norden
structures on T
∗M. We investigate conditions for these structures to
be para-Kähler (paraholomorphic) and quasi-para-Kähler. Also, some
properties of almost paracomplex Norden structures in context of almost product Riemannian manifolds are presented.
