Abstract
In this work we have shown bulk superconductivity and studied the anisotropy in both the normal and superconducting states in the quasi-one-dimensional conductor Nb2Se3. Electron-electron Umklapp scattering dominates electronic transport along the direction of Nb metal chains as well as perpendicular to it. The superconducting state is rather anisotropic with possible multiband features.
