      abstract     = {The spin of the electron is nowadays replacing the charge
                      as basic carrier of information not only in spintronics
                      applications, but also in the emerging field of quantum
                      information. Topological quantum materials, where
                      spin-momentum locking is believed to lead to particularly
                      long spin lifetimes, are regarded as a promising platform
                      for such applications. However, spin-orbit coupling, that is
                      essential to all topological matter, at the same time gives
                      rise to spin mixing and decoherence as a major obstacle for
                      quantum computing. Here, we give experimental evidence that
                      hot-spots of spin-mixing and spin-conserving contributions
                      of the spin-orbit operator coexist in an archetypal
                      topological Dirac metal, and that these hot spots can have a
                      strongly anisotropic distribution of their respective wave
                      vectors with respect to the spin quantization direction. Our
                      results can be understood within a theory that takes into
                      account the decomposition of the spin-orbit Hamiltonian into
                      spin-conserving and spin-flip terms, contributing to a
                      better understanding of quantum decoherence in topological
                      materials, in general},
