We present the -axis transverse magnetoresistance study of the spin-density-wave (SDW) ground state in the quasi–one-dimensional conductor for temperatures down to 2.2 K and magnetic fields up to 5 T. The magnetoresistance is very large and highly anisotropic. We present the clear change in the activation energy for and , which depends on magnetic field. The results can be well described by the quasi-particles with the energy gap given in the model with imperfect nesting.
