Abstract
We theoretically demonstrate that strong non Fermi-liquid magnetic oscillations of
electron-electron scattering time can exist in quasi-one-dimensional conductors under condition of
the magnetic breakdown between two open electron orbits. They are shown to be due to
electron-electron interactions in a metallic phase under condition of the magnetic breakdown and they
are beyond the Fermi-liquid theory. In particular, we consider as example the organic
conductor (TMTSF)2ClO4 and perform both analytical and numerical calculations for its known electron
spectrum. We also argue that similar oscillations of resistivity can exist in a metallic phase of
another quasi-one-dimensional organic conductor - (Per)2Au(mnt)2.
